Remote Ip Feature Phone - ESI IP 200 Installation Manual

IP Series Installation Manual
Remote Network Card (RNC)
The Remote Network Card (RNC) provides G.729A compression to support Remote IP Feature Phones
and multi-site installation using Esi-Link. The RNC is offered in two versions that can be added to
the IP 200 or IP 40. The RNC 3 provides three channels of voice compression; the RNC 12 provides
12. The RNC compresses the two-way talk path, 64 Kbps each way, into 8-Kbps talk channels. Each
compressed bi-directional channel, voice and control signaling, requires only 22 Kbps. This com-
pression makes remote connection between IP PBX and Remote IP Feature Phones practical.
Port card options
Three port cards are available for creating various system configurations:
Card What it provides
303 3 loop-start lines via an RJ-11 connector, 3 analog device ports via an RJ-11 connector
600 6 loop-start lines via two RJ-11 connectors
DLC Either 24 loop-start/ground-start/E&M/E&M DNIS/DID trunks, or 23 digital ISDN lines
(23B + 1D), via an RJ-48 connector
Note: The IP 200 and the IP 40 will have one of these cards installed in the first card slot
upon delivery.
IP Feature Phones
The IP Feature Phone is equipped with speakerphone, 16-character-by-2-line LCD display, and fixed
and programmable feature keys. IP phones provide two RJ-45 connectors – one for connecting to
the network and one for another Ethernet device – and a connector for a 64-key expansion console.
AC power is provided through a small external grounded transformer with a 12-foot cord. A 12-foot
Category-5 Ethernet cable is provided with each phone.

Remote IP Feature Phone

The Remote IP Feature Phone is virtually identical to the IP feature Phone. The physical appearance
is the same. The operation varies in only a few minor ways. The critical difference is the G.729a
processor contained with the Remote IP Feature Phone. This processor performs the voice com-
pression required to make remote IP telephony practical.
