Module descriptions
•
4-FXO
— Provides circuits for up to four analog loop-start CO lines. This card uses four CO ports.
Note:
Ground-start CO lines are not supported.
•
4-FXS
— Connects up to four analog devices, such as fax machines and cordless phones. This module
uses four phone ports and no CO ports. Each port provides a standard 24-volt, two-wire phone
connection. Only one analog device can be connected to each port.
•
D8
— Connects up to eight ESI digital phones. This module uses eight phone ports and no CO ports.
•
T1/PRI
— Provides
either
a T1 interface supporting 24 DS0 channels
or
an ISDN PRI interface
supporting 23 B (bearer) channels and one D (datalink) channel.
Note:
A jumper must be installed on pins 7 and 8 of J2 to enable ISDN PRI functions. The module
supports, and any or all of the available channels can be assigned as, loop-start, ground-start, E&M
or DNIS/DID CO types with immediate, wink-start, or dial-tone-start signaling. This module is
equipped with a built-in CSU that can be connected directly to a network interface unit, SmartJack, or
ISDN PRI. All 24 CO ports are allocated (regardless of whether they are assigned or used).
•
UIP
— Provides 63 universal IP ports which can be used for any combination of: local or remote ESI IP
phones, local or remote SIP phones, SIP COs, or ESI-Link channels. This module must be installed in the
slot closest to the rear of the MCU. This slot is labeled with white silkscreen on the main board as
UIP
MODULE
.
Note:
SIP phones and SIP COs require additional licensing.
•
G.729a
— Provides 48 G.729a sessions for use on SIP COs or ESI-Link channels. This module must be
installed in the slot closest to the front of the MCU. This slot is labeled with white silkscreen on the main
board as
CODEC MODULE
.

The maximum module capacity is also dependent on the system’s dialing plan (four-digit or three-digit).
