There are two types of stand-alone DCP data modules as shown in 

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
