DIG-LINE maintenance monitors and tests ports on digital line circuit packs or digital line media
modules and on hardware administered as a digital station on those ports. These include
stations with only a digital phone and stations with a digital phone linked to a data module.
Standalone data modules and data adaptors in standalone mode are covered by PDMODULE
(Processor Data Module).
Circuit pack maintenance is covered by DIG-BD (Digital Line Circuit Pack), the strategy for
which is described in XXX-BD (Common Port Circuit Pack/Media Module).
The following circuit packs support digital lines:

Each digital line port supports two 64 kbps information chels (primary and secondary) and one
8kbps signaling chel. Digital voice terminals always use the primary information chel, and only
one voice terminal can be connected to each port. The secondary information chel 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 chel. Figure 14: Digital Line Connectivity shows examples of digital line
connectivity.
Use only the TN754B or TN2136 circuit packs in out-of-building applications.
The TN2181 and TN2224B/CP support both modes as shown in Figure 14: Digital Line
Connectivity and Figure 15: Digital Line Connections.
