Ip Multiline Station (Sip) - NEC SL2100 Features And Specifications Manual

ISSUE 1.0
Description
The SL2100 system supports IP Terminals. IP Terminals have the similar look and functionality of
typical Multiline Terminals, but they are connected to the CPU via IP rather than by a hardwired
connection to a Digital Station port.
The following IP Multiline Terminal support IP extensions:
• IP7[ ]-8IPLD-C1 TEL (BK)
IP to TDM Conversion
When an IP Terminal calls a Multiline Terminal, Single Line Terminal, Voice Mail, or a trunk, the speech
must be converted from an IP to TDM (Time Division Multiplexing) technology. The VoIPDB provides
this function. The VoIPDB has up to 128 DSP resources on the board, each one can convert a speech
channel from IP to TDM and vice versa. It is possible for IP Terminals to talk directly to other IP
Terminals without using VoIPDB DSP resources.
IP Multiline Terminals
The IP Multiline Terminal operates the same way as a digital Multiline Terminal. The IP Multiline
Terminal has all of the features and flexibility you expect from a digital Multiline Terminal. The
difference is that the IP Multiline Terminal uses an RJ-45 for connection to the IP network, rather than
an RJ-61 connection to a 082U-B1 or 008U-( )1.
LAN Connection
The IP Terminal has two RJ-45 connections on the back marked PC and LAN. This allows the IP
Terminal and a PC to share one cable run and switch port.
If installing an IP Terminal at a location that has a PC connected to the data network, one of the
following methods can be used:
• Using a different cable:
- Leave the PC connected to the LAN.
- Patch a switch port to the new cable run.
- Connect a CAT 5 straight-through cable from the wall outlet to the LAN port on the IP Terminal.
• Sharing the existing cable:
- Unplug the cable from the PC Network Interface Card (NIC).
- Connect the cable to the LAN port on the IP Terminal.
- Connect a new straight-through patch lead from the PC NIC to the PC port on the IP Terminal.
Powering the IP Terminal
Power can be provided to the IP Terminal by the following methods:
• Power over Ethernet (PoE)
The IP Terminal (IP7[ ]-8IPLD-C1 TEL) can only be powered using Power over Ethernet (PoE)
802.3af. An external power supply (such as AC adapter) is not supported.
PoE (Power Over Ethernet) is a LAN technology that allows standard 10Base-T/100Base-TX data
cables to pass electrical current from a power source to a requesting end device.
NAPT
This function is used to establish SIP communication with the main device and RTP communication
among SIP Terminals through the NAT on an IP network.
