What is the SL2100?
The SL2100 system consists of a chassis unit with a dedicated slot for the CPU
card and four universal slots for interface cards. Each universal slot supports an
extension interface card, optionally each extension interface card can have a trunk
interface daughter card mounted.
The chassis unit is ventilation cooled (no fan) and can be wall mounted or rack
mounted with the optional rack mount shelf.
Up to three chassis units can be connected together to provide a total of twelve
universal slots.
Interface cards are available for Analogue and ISDN trunks, proprietary SL2100
terminals and analogue telephones.
SIP Trunks, SLNet and IP terminals are supported without the need for additional
system hardware as eight VoIP resources are built in to the CPU card. VoIP
resources can be expanded to 16 by adding the optional VOIPDB card and further
to 128 with licenses.
InMail voicemail is also available either using the built in storage of the CPU-C1-A or by adding the optional SD
card.
The built in InMail with the CPU-C1-A card provides 4channels and 2hours of storage, this can be expanded to
15hour or 120hour by adding the SD card to the CPU.
The CPU-C1 requires the SD card installed to provide InMail voicemail.
Both CPU’s have built in VRS with 4 channels and 100 messages with 2hours message storage.
All equipment will operate in the default/factory setting when the SL2100 is installed.
With the default settings:
Each telephone will function and is assigned an extension number.
Calls received on the trunk lines will ring at telephone number 200.
Each telephone can make outside calls by dialling 9.
Each trunk line is presented at a Function Key with busy lamp indication.
SLNet is not configured
SLNet included in this guide
Only the configuration of SLNet is covered in this guide.
SLNet provides these networking features:
Centralised InMail voicemail
Desk to Desk calling with Caller ID and name display
Sharing trunk lines with remote systems
Extension busy lamp information
Shared Park Hold orbits
SLNet is available for SL2100 systems only, each system should have the same level of Main Software installed.
SLNet is supported with Main Software R1.5 or later.

NEC SL2100 Communication System
Quick Install Guide –SL2100 SLNet rev1.0 6
SLNet Overview
SLNet allows for networking between up to 50 SL2100 systems. Interconnected with VOIP, each phone system
becomes a node on the network that can communicate with any other phone system node. Systems can be
installed separately in the same building, or in remote locations connected via a suitable network.
SL2100 SLNet Channel Capacity
The capacity of SLNet channels is not limited by the quantity of IP or TDM ports installed.
The SL2100 supports up to 128 SLNet channels per network node (licenses required for each node).
Each SL2100 system within the SLNet Network must have sufficient SLNet channel licenses BE116748 installed
to provide the quantity of simultaneous voice calls required by the customer.
Each SL2100 system will also require sufficient VOIP resources to support the simultaneous calls.
SLNet Numbering Plan
The numbering plan must be unique for all nodes within the SLNet Network, each node must have a unique
extension number range, this is defined by the leading two digits unless you intend to use F-Route.
F-Route can be used to create a numbering plan that can use any number length to define the remote extension
numbers

NEC SL2100 Communication System
Quick Install Guide –SL2100 SLNet rev1.0 7
SL2100 VOIP Resource Capacity
The SL2100 CPU cards have 8 VOIP resources built in, these can be expanded further by adding the VOIPDB
card (BE116500) and VOIP channel licenses (BE116744).
Adding the VOIPDB card provides 16 VOIP resources, the VOIP channel license provides an additional 16
resources up to 128 channels maximum.
Note - The VOIPDB card must be installed in order to use the VOIP channel license.

This example shows the minimum quantity of VOIP resources for each SL2100 system if the customer requires
the maximum quantity of simultaneous SLNet calls to be available between each node.
No trunk channels are included in the example.
SL2100 Configuration
Currently only PCPro supports the setup of SLNet configuration items, System Phone or WebPro does not
support SLNet items.

Network Requirements
SLNet should be deployed on networks connected by some form of Point-to-Point connection such as a VPN,
MPLS, or other Point-to-Point circuit.
The voice quality of VoIP depends on variables such as available bandwidth, network latency, and
quality of service initiatives (QoS), all of which are controlled by the network and internet service
providers. Because these variables are not within NEC's control, the performance of the user’s IP based
voice solution cannot be guaranteed. Therefore, NEC recommends connecting the VoIP
equipment through a fully managed data network with Quality of Service (QOS) implemented.
For a network to be suitable for VoIP it must pass specific requirements.
The requirements are:
• One way delay must not exceed 150 ms
• Round trip delay must not exceed 300 ms
• Packet loss must not exceed 1 %
• Data switches must be manageable
• No half-duplex equipment may be present in the network
• Routers must provide QOS
Depending upon how the QOS policies are built in the network, assignments may be needed in the CPU
(PRG 84-10).
• Adequate bandwidth for the estimated VoIP traffic must be available
See below chart for bandwidth calculations.
Below is a chart that shows the average bandwidth per VoIP call over Ethernet

As an example, if one site plans on making a maximum of 16 calls across the network using G.729 with
a 30 ms packet size, there must be a minimum of 376 kbps available for voice traffic. The QOS policy
for this network should allow for 376 kbps to be set aside for voice prioritization.

Conditions
1. SLNet is not supported through NAT, only Point-to-Point connection such as a VPN, MPLS, or other
Point-to-Point circuit.
2. SLNet is only for networking SL2100 systems together.
3. Hold, Transfer, and Park recall timers will follow the timer of the system where the call is on hold (Trunk
and Station). For example, a user in Site A calls a user in Site B. Site B answers the call and places the
call on hold. The hold recall time is based on Site A because the call on hold is in Site A and not site B.
4. The allowing or denying of Class of Service features in an SLNet Network must be performed network
wide. For example, if users in Class of Service 1 at site 1 want to block the Camp On feature a change
will have to be made in Class of Service 1 of all systems in the network.
5. When a terminal or trunk is placed on hold, the Music on Hold comes from the system where the
terminal or trunk resides.
6. When Multiple Voice Mails are installed in the network, each site must have a unique Voice Mail pilot
number. The pilot number assigned must be within the routable extension number range in all sites
throughout the network.
7. When each site has its own Voice Mail system, a user in one location cannot call the Voice Mail pilot
number that resides in another system.
8. When each site has its own Voice Mail system, a Voice Mail Message Line key (Program 15-07 : key 77)
cannot be programmed for an extension in a Remote system.
9. Virtual Loopback trunks are not supported across SLNet
10. SMDR information is collected in the system where the trunk resides. If a user in Site A accesses a CO
trunk out of Site B, this call is reported in Site B's SMDR and not in Site A's SMDR.
11. When a networked internal call forwards to Voice Mail (Centralized or Individual Voice Mail) the user will
not be able to perform any dialing options to dial out of the mailbox. The associated dial action table
cannot be accessed unless the call originates from a CO trunk
12. Built-in Automated Attendant and Centralized Voice Mail cannot be used in the same system
13. Calls (Intercom or Trunk) routed across the SLNet network cannot be answered by the Built-In
Automated Attendant
14. Directory Dialing will not list extension numbers in remote SLNet systems
15. An operator extension (Program 20-17) cannot be assigned to an extension in a Remote SLNet system.
The operator for each site must reside in their own local system
16. Mobile Extension is not supported for calls across the SLNet network
17. When transferring a caller to a remote SLNet extension via the press of a DSS key on a 60 button DSS
console, without pressing Transfer first, you must press the DSS key twice to complete the transfer.
