Figure 46: Digital Line Connections
Only 2-wire Italtel Digital Telephone Models 1 and 2 (IDT1/2) or DAs can directly connect to a
TN2136 circuit pack. Avaya DCP (4-wire) digital voice terminals and data modules can connect
to these circuit packs via Italtel’s 2/4-wire adapter. DAs operate in either of 2 modes, and are
covered by different MOs:
S8300 / G700
For Media Gateway-level maintenance, see MG-DCP (Digital Line Media Module) on
page 1593, the strategy for which is described in XXX-BD (Common Port Circuit Pack/Media
Module) on page 2539.
Note:
Note: DIG-LINE MO is provided for G700, but this MO only partially supports the G700’s
MM712 DCP media module.
