1 Where P is the port network number (1 for PPN and 2 or 3 for EPN); C is the carrier
designation (for example, A, B, C, D, or E); SS is the address of the slot in the carrier
where the circuit pack is located (for example, 01, 02, etc.); and pp is the 2-digit port
number (for example, 01).
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 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 8kbps signaling channel. Digital voice terminals always use
the primary information channel. Thus only one voice terminal can be connected
to each port. The secondary information channel can be used to connect a data
terminal via a Digital Terminal Data Module (DTDM) or a Data Adaptor (DA). All
other devices currently supported by Digital Line circuit packs communicate on
the primary information channel. Figure 10-26 shows examples of digital line
connectivity.
Only the TN754B or TN2136 should be used in out-of-building applications.
