DIG-LINE (Digital Line)
DIG-LINE maintenance monitors and tests ports on Digital Line circuit p acks and
the hardware connected to those ports for lines admin istered as a digital station.
These include stations with just a digita l voice terminal and stations with a d igital
voice terminal and a linked data module. Stand-alone d ata modules, and d ata
adaptors in stand-alone mod e, are covered by the PDMODULE and TDMODULE
maintenance objects. Circ uit pack-level maintenanc e is covered by DIG-BD
whose strategy is describ ed in the XXX-BD section of this chapter. The following
circuit packs support digital lines:
Each digital line port supports two 64 kbps information channels (primary and
secondary) and one 8 kbps signaling channel. Digital voic e terminals always use
the primary information cha nnel. Thus only one voice terminal can b e connected
to each port. The second ary information channel ca n be used to connec t a data
terminal via a Digital Terminal Data Module (DTDM) or a Data Adap tor (DA). All
other devices currently sup ported b y Digital Line circuit p acks communic ate on
the primary information chann el. Figure 10-26 shows examples of dig ital line
connectivity.
