Line Cards
The diverse applications that the XMU+ can execute is made possible by the
various line cards that can be installed. Each line card must be cabled individually
to the PBX, transmitter, or amplifier. This section describes the procedures for
cabling XMU+ line cards.
To cable Hybrid Analog line cards
Hybrid Analog line cards give the XMU+ the ability to provide Auto-Attendant/
Audiotex announcements, 1-800 ACD call routing, and ACD/UCD intercept messages.
Hybrid Analog line cards replace the Passive and Interactive Line Cards by combining
their features. Cable the Hybrid Analog line card using the steps shown below.
1. Verify that PBX line cards are configured for the appropriate XMU+ application
(Call Processing, Auto Attendant, or ACD). See About XMU+ Operating Modes
on page 68 for more information.
2. Punch down wires from PBX to the punch block.
3. Punch down wires from XMU+ to the punch block.
4. Cross connect the wires in the punch block as per the following PBX tables:
Call Processing/Auto Attendant Applications on page 56. This table is also
used to cable Interactive line cards in older XMU units.
ACD Applications on page 57. These tables are also used to cable Passive
line cards in older XMU units.
To cable Low Impedance cards
Low Impedance XMU+ line cards are used to provide ACD/UCD messages. However,
Low Impedance cards can connect one (1) passive port to twenty-four (24) PBX
trunks. Low Impedance line cards can only be used with Nortel PBXs.
1. Verify that PBX line cards are configured for the appropriate ACD application.
See About XMU+ Operating Modes on page 68 for more information.
2. Punch down wires from PBX to punch block.
3. Punch down wires from XMU+ to punch block.
4. Cross connect the wires in the punch block as per the appropriate (Nortel only)
ACD Applications table on page 64.
To cable T1 line cards
T1 XMU+ line cards connect to a T1 communication link on a PBX to provide the
XMU+ with 24 T1 user channels.
