IP Multiline Station (SIP)DescriptionThe SL1100 system supports IP Terminals. IP Terminals have the same look and functionality oftypical Multiline Terminals, but they are connected to the CPU via IP rather than by a hardwiredconnection to a Digital Station Port.The following IP Multiline Terminals support IP extensions:• IP4WW-24TIXH-C-TEL (WH) / IP4WW-24TIXH-C-TEL (BK)IP to TDM ConversionWhen an IP Terminal calls a Multiline Terminal, Single Line Terminal, Voice Mail, or a trunk, thespeech must be converted from an IP to TDM (Time Division Multiplexing) technology. The VoIPDBprovides this function. The VoIPDB has up to 32 DSP resources on the unit, each one can convert aspeech channel from IP to TDM and vice versa. It is possible for IP Terminals to talk directly to otherIP Terminals without using VoIPDB DSP resources.IP Multiline TerminalsThe IP Multiline Terminal operates the same way as a digital Multiline Terminal. The IP MultilineTerminal has all of the features and flexibility you expect from a digital Multiline Terminal. Thedifference is that the IP Multiline Terminal uses an RJ-45 for connection to the IP network, rather thanan RJ-61 connection to a 084M or 080E.LAN ConnectionThe IP Terminal has two RJ-45 connections on the back marked PC and LAN. This allows the IPTerminal 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 thefollowing 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 TerminalPower can be provided to the IP Terminal by one of the following methods:• Local PowerThe IP Terminal has a connector on the back for external power. This is supplied by an AC adapterthat outputs +27VDC requiring a separate power outlet per IP Terminal. Loss of power in thebuilding will prevent the telephones from functioning.Only use the NEC supplied power supply.ISSUE 2.0 SL1100Features and Specifications Manual 1-423I
