Stand-Alone DCP Data Modules
There are two types of stand-alone DCP data modules:

MPDM Modular Processor
Data Module
MTDM Modular Trunk Data
Module
1. Early versions of these data modules were referred to as PDMs and TDMs, respectively. Later models are
designed to provide a variety of interfaces by using interchangeable modules and are thus called modular
data modules. Both types are supported by the tests described in this section
Data Adapters
TN2136 circuit packs use IDCP signaling and a DAA2 Data Adaptor (DA) to
interface to DTE. DAs can operate in either of two modes which are covered by
different MOs:
