ESI Communications Servers Hardware Installation Manual
When working with a T1 line
•

Ground start
•
E&M (including E&M–DID/DNIS/ANI) — When an E&M trunk is selected, the choices for outgoing
signaling type are immediate start, wink start and dial tone start; and the incoming signaling type choices
are immediate start and wink start. The E&M trunk can be set for 2-way traffic, inbound traffic only or
outbound traffic only.
The DID and DNIS/ANI translation table allows the translation of DID/DNIS digits to an ID, mailbox, extension
or department. See below for the number of entries that can be programmed in the table:
There is also an entry for exceptions in the table. This allows reroutes of any DID/DNIS calls that aren't
programmed or detected to an ID, mailbox, extension or department and defaults to the operator.
The card supports the following framing format and line coding:
•
ESF/B8ZS (default)
•
SF(D4)/AMI
•
ESF/AMI
•
SF/B8ZS
Line compensation (or line build-out) is provided as necessary between the CSU or Smart Jack
ESI Communications Server. There won't be any support for pulse dialing; all incoming dialing will default to
DTMF digits.
When working with a PRI line, the DLC (i.e., the DLC, DLC12, or DLC82) supports these switch protocols:
•
National-NI2 (default)
•
Nortel-DMS100
•
AT&T/Lucent-5ESS
•
Siemens-EWSD
DID for the PRI is an enable/disable field. When DID is enabled, the PRI pilot table becomes active and works
in combination with the DID tables.

SIP trunks

For SIP trunking applications, an ESI Communications Server must use a compatible SIP24 card. Each ESI
Communications Server has a different maximum number of system-wide SIP24s (see "Port card options,"
page A.4). Partial SIP applications are supported through line programming.
Supported SIP trunks are:
•
Broadvox ND
•
Broadvox NS
