DIG-LINE (Digital Line)
DIG-LINE maintenance monitors and tests ports on digital line circuit packs and
the hardware connected to those ports for lines administered as a digital station.
These include stations with just a digital voice terminal and stations with a digital
voice terminal and a linked data module. Standalone data modules, and data
adaptors in standalone mode, are covered by the PDMODULE and TDMODULE
MOs. Circuit pack-level maintenance is covered by DIG-BD whose strategy is
described in
‘‘XXX-BD (Common Port Circuit Pack)’’ on page 8-1872
Only the TN754B or TN2136 circuit packs should be used in out-of-building
applications. For important information pertaining to protection required for
out-of-building digital voice terminals, refer to DEFINITY Enterprise
Communications Server Release 5.4 Installation and Test for Multi-Carrier
Cabinets.
Only 2-wire Italtel Digital Telephone Models 1 and 2 (IDT1/2) or DAs can directly
connect to a TN2136 circuit pack. Lucent DCP (4-wire) digital voice terminals and
data modules can connect to these circuit packs via Italtel’s 2/4-wire adapter.
DAs can operate in either of two modes, and they are covered by different MOs:
Digital line maintenance interacts with digital line circuit pack (DIG-BD)
maintenance. The health of the digital-line circuit pack can affect the results of
DIG-LINE testing. Keep this in mind when investigating digital-line problems.
