NEC SL1000 Licensing Process Explained

Today i explained in details on the entire process of how do you purchase the NEC SL1000 licenses, activate the licenses and load it into the NEC SL1000;


  1. Purchase of NEC SL1000 Licenses
    • First kindly refer to my earlier posting [SL1000 License Structure Explained] to understanding the usage of the NEC SL1000 Licenses, and when do we need the licenses
    • One important thing over here is you will need to have the NEC License Management System (LMS) portal login account tagged to your company, or if you are one of the 3-tier partners who purchase the NEC SL1000 through your reseller then make sure they have the NEC LMS Login ID
    • The reason here is because upon the purchase of the NEC SL1000 licenses, email notification (to the ADMIN role defined during account creation) will be send by the NEC LMS portal notifying that the NEC SL1000 license purchase has been processed and ready for activation

  2. Activation of NEC SL1000 Licenses
    • *Assuming you have the NEC LMS Portal Login ID 
    • Once you receive the email notification that your PO for NEC SL1000 has been processed and ready for license activation, you will need to login to this portal URL; http://asialic.necinfrontia.com/license/ (for Asia market), 
    • Ok this is what you need from the NEC SL1000 => Hardware Keycode (see the picture on the right)
    • This is the brief overview of license activation in the NEC LMS portal;
      • Customer ID creation
      • Tagging of the NEC SL1000 Hardware Keycode to the newly created Customer ID
      • Attaching NEC SL1000 Licenses to this Customer ID
      • Activate the NEC SL1000 Licenses
      • You will then be prompted to download the NEC SL1000 license file (format: .lic), please store it locally in your PC/laptop

  3. Loading of NEC SL1000 Licenses into the NEC SL1000 Main KSU Chassis
    • Next we discuss more on how to load the NEC SL1000 license file into the NEC SL1000 system
    • Primarily there are 2 methods to load the NEC SL1000 license file into the NEC SL1000 system (main chassis);
      • First method: Using PCPro
        1. Login to the NEC SL1000 using the NEC SL1000 PCPro
        2. Connect to the NEC SL1000 system
        3. In the menu bar click on 'Communications' => 'Feature Activation'
        4. A small window showcasing all the current NEC SL1000 license activation status for each individual licensed features 
        5. Click on 'Load File' and then navigate to the place where you have saved your NEC SL1000 license file and click Open
        6. You will now see the following message 'PCPro was successfully registered'
        7. NEC SL1000 license successfully activated
      • Second method: Using WebPro
        1. Launch a Web Browers Internet Explorer
        2. Set the URL to point to the IP address of the NEC SL1000; default IP address is 192.168.0.10/24
        3. Perform a NEC SL1000 login process (username: tech   password: 12345678)
        4. Once login successfully look for the icon 'Feature Activation' under the Administration section
        5. You will see the IE refreshes to showcase all the current NEC SL1000 license activation status for each individual licensed features 
        6. Click on the 'Browse' button then navigate to the place where you have saved your NEC SL1000 license file and click Open
        7. You will now see the following message 'License registered successfully' in the top right-hand corner of the IE window
        8. NEC SL1000 license successfully activated

NEC SL1000, Mobile Extension Feature

http://www.fileserve.com/file/MjdWsNv/NEC_SL1000_Mobile_Extension_Feature.pdf

http://www.mediafire.com/?7248cyzc88i4646

One of the great feature of the NEC SL1000 is the Mobile Extension feature. This feature gives the user mobility access meaning that they are always contactable via their mobile phone. Below shows you the overview of the usage of this feature, Mobile Extension;
  • Feature: Mobile Extension
  • Operation Overview : The user mobile number is registered to the NEC SL1000 system and this user shall be able to receive both internal/external calls via his DDI number (ISDN number). This gives the user the mobility feature whereby they are always contactable via their office number instead of their own personal mobile which gives them privacy. Mobile Extension feature is a little bit similar to DISA (Direct Inward System Access) service but without the need to enter password.    
  • Operation (Receiving Calls): Callers (internal/external) will dial to this user's DDI number given by the user. Upon receiving the call at the NEC SL1000 system it will recognize that the call for this user based on DDI mapping will need to be re-directed out (via System Speed Dial method) to this user since he is a Mobile Extension user. At the point the user's mobile phone will start to ring, and he will see his own DDI number as Caller-ID. Based on the calling ID, he knows that this incoming call is call coming from his office (meaning business call). When he pressed the Answer button on his phone he will hear MOH/system tone, at this point he will simply press * to answer this call (voice communication). Since he is a SL1000 user, he is able to perform basic phone features like hold the call, transfer to another number, etc
  • Operation (Making Calls): The Mobile Extension user will first use his mobile phone and dial in to his own DDI number. The NEC SL1000 system upon receiving this call and based on his calling ID information he is identified as a Mobile Extension user and the system will give him a second tone, system tone (similar to DISA without the need to key in password). At this point this user is virtually as if he is in his office, he is able to make a internal call, seizure the trunk to make an outgoing call, call his voicemail system, etc
  • Good for users: Office workers who are always on the move, Sales Staff
  • Good for Office: Since there may be certain office workers who are allowed to make mobile claims (both local and international calls), the company can better control the tariff cost for making overseas calls by requesting the user to call back to the company SL1000 system and from there make an overseas call where there is better corporate rating for such calls
  • License Required: Yes. Default comes with 4 licenses, additional licenses can be purchased for up to 32 defined Mobile Extension users
  • License: SL-SYS-MOBILE-1 LIC  


I strongly feel that this feature is a very good feature whereby mobility access is extended to users via the public network whenever there is network coverage.

What is NEC SL1000 all about?

The NEC SL1000 Smart Communications Server was launched recently in the world by NEC Corporation around Feb 2011. In fact there is a series for the product in different region, we have the SL1000 (in Asia, EMEA) and the SL1100 (in America). Collectively they are known as the NEC SL1000 series range of key telephony systems.

The major difference between SL1000 and his brother SL1100 is that for SL1000 the extension ports are all hybrid, meaning that the installer can plug in an analog or digital phone into the port and it will work for both cases. As for the SL1100 there is a clear distinction in terms of extension ports; analog & digital extensions ports.



This SL1000 series enables customers to have remote extensions through the use of NEC ip phone 24TIXH type. This is really a good feature for customers who have satellite/remote offices hosting a few numbers of staff.

The target market segment is the smaller than SMB market, with maximum support of 128 users. The pricing of the SL1000 is also very economic bearing in mind of the small business owners who needs a smart office communications tool yet at the same time is cost effective and easy to use.

In terms of market competition SL1000 major competitor will be the Panasonic KTS systems. Both of them are Japanese brand with a long history of good and quality built voice communications system. As such most of the time the primary deciding factor for the customers would be the price and design of the phone sets.

Personally I feel that with the recent launch of SL1000 and the UNIVERGE SV8000 series, it truly target all the enterprise users, from the very small users 2-3 all the way to large organizations < 5000 users, with strong seamless phone features in a networking environment. Do give me your thoughts on this new product from NEC, the NEC SL1000 Smart Communications Server.

SL1000 License Structure Explained (VRS + Voicemail)

There are some confusion over the number of VRS and Voicemail port access, especially on the usage of default number of ports and license usage. 

I will do a detailed explanation over here. 


First Thing we need to understand the hardware requirement for both VRS & Voicemail. In the SL1000 hardware lineup, below shows you the hardware required;
  • PZ-VM21 (serves as a holder to put in the Compact Flash CF card) - CF slot
  • Type of CF available (either of the 3 cards);
    • IP4WW-CFVRS-C1 (only have VRS functionality) = 512MB
    • IP4WW-CFVMS-C1 (both VRS & Voicemail Functionality) =512MB
    • IP4WW-CFVML-C1 (both VRS & Voicemail Functionality) =1GB
Just treat CFVMS as VM short (approx. 15 hours storage), CFVML as VM long (approx. 40 hours storage). 

Second Thing let's understand the default number of ports for both VRS/Voicemail. Please see below;
  • IP4WW-CFVRS-C1, default 4 ports access (VRS)
  • IP4WW-CFVMS-C1, default 4 ports access (VRS) + 2 ports access (VM)
  • IP4WW-CFVML-C1, default 4 ports access (VRS) + 4 ports access (VM)
Now that you understand the default number of ports. Lets discuss further on expanding the ports access.

Third Thing let's look into the ports expansion for both VRS + VM. Please see below;
  • IP4WW-CFVRS-C1, default 4 ports access (VRS)
  • IP4WW-CFVMS-C1, default 4 ports access (VRS) + 2 ports access (VM)
  • IP4WW-CFVML-C1, default 4 ports access (VRS) + 4 ports access (VM)

  • FOR VRS PORTS: To expand up to 16 ports access, simply you just need to buy the memory card IP4WW-MEMDB C1 and insert it into the CPU card. By this action you will have automatically 16 ports for VRS access. This statement applies for all the 3 CF cards
  • FOR VM PORTS: To expand both CFVMS & CFVML voicemail ports access from 2 and 4 ports respectively, you will need to purchase the following license SL-VM-CHANNEL-2 LIC. This license per quantity will give you 2 ports expansion. You can expand the voicemail port access up to a maximum of 16 ports access. IMPORTANT: YOU WILL NEED THE MEMORY CARD IP4WW-MEMDB C1 when you are expanding beyond 8 ports voicemail access

SL1000 License Structure Explained

Basically the SL1000 license structure is categorized into the following system feature grouping;

  • VoIP
    • SL-IP-SIPTRK-1 LIC (up to max. 16 IP Trunks, SIP/H.323)
    • SL-IP-SIPEXT-1 LIC (up to max. 16 IP phones, 3rd-party standard SIP phones, no license is required for NEC IP phone IP4WW-24TIXH-C-TEL)
  • VoIP (Enhanced) 
    • SL-IP-ENCRYPTION LIC (turn on feature, to encrypt the RTP packet for IP phone communications) 
    • SL-IP-NAPT LIC (turn on feature, to enable remote IP extension connecting back to SL1000 via NAPT method)
  • VM 
    • SL-VM-CHANNEL-2 LIC (max. up to 16 Voice mail ports access, * i will explained more in details as it is a little bit tricky on this part)
  • VM (Enhanced)
    • SL-VM-ADVANCE LIC (turn on feature, to have for example voice-to-email feature, meaning user can retrieve their voicemail using their email client although it is not a true unified messaging system. it simply forwards a copy of the voicemail as wav. file to the email inbox)
  • Mobile Extension 
    • SL-SYS-MOBILE-1 LIC (max. up to 32 defined users, this feature is very useful and it gives the users mobility with pbx phone features, *i will explain more in details in my next posting)
  • Hotel/Motel 
    • SL-SYS-HOTEL LIC (turn on feature, you will need to activate this license if you want to make use of the hotel/motel features in SL1000)
Having said and done, which license you think is not very useful? Personally i feel that the enhanced feature for VoIP is not very useful, encryption & NAPT. 

SL1000 Data Sheet

http://www.fileserve.com/file/2C94kuF/NEC_SL1000_Datasheet.pdf

http://www.mediafire.com/?7m7adi7eqtgptgm

This SL1000 data sheet is very informative, it gives the installer/sales staff as good overview of the SL1000 product specification itself.

Information like product schematic overview, system configuration, system capacity, operating conditions, electrical & mechanical specifications and most importantly the system features.

In terms of system features-wise it is pretty similar to NEC UNIVERGE SV8100 except that it don't inherit the following features;


  • Embedded ACD & ACD-MIS
  • Hotel PMS (it don't integrate to hotel pms, just standalone hotel features like check-in/out,etc)
  • Networking Features (No K-CCIS, No Netlink, No Aspilanet, No E&M Tie, No nothing basically) - ONLY SIP/H.323 IP Trunk or Analog FXO/FXS Connection Type
  • Applications Blades (since hardware-wise it is different, so no UM8000, no In-skin Router/Switch, In-skin UCB)
  • No Support also for UNIVERGE DT300/700 series terminals

Remote Access for SL1000

The SL1000 system allows remote access for engineers to perform their maintenance tasks, MACD tasks, etc.

Below shows you what is required in terms of hardware / setup;


  • Hardware: PZ-VM21 mounted on CPU card
  • Setup procedures, see below;


STEP 1:

For PZ-VM21 the modem related setting will be as below:



(for Analog CO trunk)



               PRG11-15-14 746 (assign any unique service code) – please check your numbering plan, have to be unique code in the system

PRG22-02-01 assigns Trunk to “DIL”

PRG22-07-01 set DIL destination “746”



(for ISDN trunk)



               PRG11-15-14 746 (assign any unique service code) - – please check your numbering plan, have to be unique code in the system

PRG22-02-01 assigns Trunk to “DID”

PRG22-11-01 map external ISDN DDI number to internal , in this case ‘746’





STEP 2:

Refer to attached http://www.mediafire.com/?bnx3ki4s9kjzdwk

How to output SMDR information for SL1000 to 3rd-party call accounting software

To connect to 3rd-party call accounting software (call billing purposes), the SL1000 need to output SMDR (station message details record) details to the application for data records and for reports generation.

This is where the difference between SL1000 and Aspila Topaz comes about.

For Aspila Topaz it is possible to output the SMDR information via IP or serial methods, while for SL1000 (sames goes for SV8100) the only output method is IP.



Below is the information on the setup;

Ok here are the items you need to do to get the SMDR output from SL1000  CPU;

            At SL1000
PROG 10-12-01/02: confirm your IP address given for the CPU
PROG 35-01-01: Output Port Type (select: LAN)
PROG 10-20-05: SMDR Output (input: 60010)
PROG 14-01-06: SMDR Print-Out (checked)
Repeat for all the trunks necessary
Reboot SL1000

At PC (using Hyperterminal)
Select Connection Type: TCP/IP
Input ip address of the SL1000 CPU, port number: 60010


Testing
Just pick up the handset, press ‘9’ to seizure trunk and input digits
The Hyperterminal screen will show the details after the call has been completed

Understanding SL1000 Deployment

http://www.fileserve.com/file/6KqvJqX/[1a]_NEC_SL1000_Deployment_Scenarios_V2.pdf

I have a contact in Asia who pass me this document for me to understand the different deployment scenarios for SL1000. Inside provides valuable information on the various deployment scenarios;

  • Pure TDM (with/without licenses)
  • Pure IP (with/without licenses)
  • License Usage (VoIP/VRS/Voicemail/Mobile Extension/Advanced InMail/Hotel)


Take note that for SL1000 it does have hotel/motel features (check-in/out, room cut-off,etc) and you will require the hotel license if you need to use the feature. And also SL1000 is deployed as a standalone without connectivity to the PMS (Property Management System). 

SL1000 Retro Fit (To Support old Aspila Topaz digital phones, TEL2)

Officially the existing Aspila Topaz digital phones are not supported by NEC. I guess this statement has angered many installers and existing customers as SL1000 is seen by all as the replacement for Aspila Topaz.

With this thing in mind, recently there was a announcement for the installer to enter special commands in order to support the existing Aspila Topaz phones.

Here are the details;

In case if you may require to offer the connectivity of Topaz keyphone to SL1000 for your
commercial demand, the following program command shall be used:
PRG 99-03-60: Set to “1” (Default: 0)



(Note)
- Topaz keyphone has to be TEL2 type only. (TEL1 type is not supported)
- This is applicable from “1.2” version of main software which applied from April/2011
production.
- If the Topaz keyphone was connected before change the above data, then plug off and on
for the line code shall be required per extension.

==> NEC's Corp stand on the usage of the Topaz phones;

a) Any voice and acoustic issue, such as Transmit/Receive/Side-Tone level, Echo/Noise level,
shall not be supported in case of Topaz keyphone (TEL2).
b) NEC Japan will not nominate Topaz keyphone as SL1000’s lineup in any Test Reports.
c) In case if any future enhancement shall be applicable on Navigation key of SL1000
keyphone, then it shall not be supported since physically not there.
