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. Stand-alone data modules, and data
adaptors in stand-alone mode, are covered by the PDMODULE and TDMODULE
maintenance objects. Circuit pack-level maintenance is covered by “DIG-BD”
whose strategy is described in the "XXX-BD (Common Port Circuit Pack)" section.
Only the TN754B or TN2136 should be used in out-of-building applications. For
important information pertaining to protection required for out-of-building digital
voice terminals, see

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. 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 which are covered by different MOs:
Digital line maintenance interacts with digital line circuit pack (DIG-BD)
maintenance, and results of DIG-LINE testing can be affected by the health of the
digital line circuit pack. Keep this in mind when investigating digital line
problems.
There are instances where the service state of a station is mentioned. It is helpful
to understand what is meant by the different service states that may exist. The
different service states which apply to digital line station are explained as follows:

1. UU is the universal cabinet number (1 for PPN, 2 -44 for EPNs). C is the carrier designation
(A, B, C, D, or E). SS is the number of the slot in which the circuit pack resides (01 to 21).
pp is the two digit port number (01, 02, ...).
