ESI Communications Servers Hardware Installation Manual Overview
A.6
• SL-DLC82 — (ESI-50 only.) Provides an ISDN PRI interface supporting 23 B (bearer) channels, one D
(datalink) channel, eight digital stations, and two analog devices.
A jumper on this card must be plugged onto pins 7 and 8 of J3 to enable ISDN PRI functions.
Any (or all) of the 23 available channels of the PRI span can be assigned, and the card supports loop-start,
ground-start, E&M and DNIS/DID trunk types with immediate, wink-start or dial-tone-start signaling.
This card is equipped with a built-in CSU that can be connected directly to a network interface unit,
SmartJack, or ISDN PRI. Up to eight ESI digital phones and up to two analog phones can be connected
to the card. All 24 CO ports are allocated (regardless of whether they are assigned or used).
• 482 — (ESI-50 [and ESI-50L] only.
1
) Provides circuits to connect up to four loop-start CO lines, eight ESI
digital phones, and two analog station ports. The CO line ports support standard CO and Centrex loop-
start lines; ground-start CO lines are not supported. Only one analog device can be connected to each
analog station port. This card uses 10 station ports and four CO ports when installed.
Notes: The main board comes in a four-line, eight-digital station, two-analog port configuration. You can add
three 482 port cards on an ESI-50. Therefore, the system can have the following configurations.
— 4  8  2: Base Cabinet (main board only)
— 8  16  4: Base Cabinet with one additional 482 port card.
— 12  24  6: Base Cabinet with one additional 482 port card and an Expansion Cabinet
with one 482 port card.
— 16  32  8: Base Cabinet with one additional 482 port card and an Expansion Cabinet with
two 482 port cards.
The maximum ESI-50 configuration — if an SL-DLC82 is used in slot 2 and the built-in IVC (see next
item) uses all 12 local IP channels — is 35 x 44 x 8.
• SL-IVC 12 — (ESI-50 only.) The ESI-50’s built-in SL-IVC 12 can support up to 12 IP channels, which support
up to 12 local IP stations, or up to eight remote IP channels. Local IP, remote IP, and Esi-Link channels
can be used in various combinations, which are activated in blocks of four for local IP, singles for remote IP,
and blocks of four for Esi-Link. Here is an example of some possible IVC 12 channel combinations:
– Eight all Esi-Link.
– 12 all local IP.
– Eight Esi-Link, four local IP.
– Four Esi-Link, four local IP, four remote IP.
Important: The SL-IVC 12 is part of the ESI-50 main board; it is not available as an add-on port card.
• CS-SIP24 — Provides 24 SIP trunk ports and supports ESI Mobile Messaging delivery of .WAV files to
e-mail addresses.
• CS-SIP8 — Provides eight SIP trunk ports and supports ESI Mobile Messaging delivery of .WAV files to
e-mail addresses.
• CS-ASC (Application Services Card) — Supports ESI Mobile Messaging delivery of .WAV files to
e-mail addresses. Also supports the storage of video recordings, audio recordings, SMDR records, and
fob events.

The 482 card also is used by ESI’s C-Plus and IVX S-Class (Generations I–II) systems.
