Error log entries and tests also apply to TDMODULE.

The PDMODULE and TDMODULE MOs monitor and test Digital Line circuit pack ports that are 
connected to Data Communications Equipment (DCE) or Data Terminal Equipment (DTE). DCE 
include processor data modules (MPDM) and Data Adaptors (DA). DTE include trunk data 
modules (DTE). These stand-alone data modules provide interfaces between DCP ports on the 
Digital Line circuit packs and data equipment such as terminals, host computers, and data 
modems. (See the following list and figure.) Data modules are used for dial-up and permanent 
circuit-switched data calls.
Digital Line circuit packs also connect to digital terminal data modules (DTDMs), which work in 
conjunction with a voice terminal. Those configurations are covered by the DIG-LINE MO. 
Circuit pack-level maintenance is covered by DIG-BD whose strategy is described in the 

Digital line circuit packs include the TN754, TN754B, TN413, TN2136. See DIG-LINE for more 
information about the characteristics of these circuit packs.

Note:

 / 

: Although the PDMODULE/TDMODULE MO is provided for a G700 

media gateway, this MO only partially supports the G700’s MM712 DCP media 
module.

1. Digital Terminal Data Modules (DTDM), and Data Adaptors (DA) in linked mode are considered part 

of the Digital Line MO. See the DIG-LINE section for maintenance of these devices. DAs in 
stand-alone mode are included in PDMODULE.

Some of the alarms that are logged due to PDMODULE and TDMODULE test failures may be 
related to circuit-pack problems reported during DIG-BD testing. See
