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

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
