DDM Network Adapter TA Connections
The DDM network adapter (Figure 5-4) supports high speed serial data connections in the V.35, RS-449 and
RS-530 formats. Connections may be dedicated (direct connect) or dialed using the RS-366 dialing protocol. The
DDM does not connect directly to the network, but connections to T1, Switched 56/64 and ISDN networks can
be made by using a multiplexer, terminal adapter, IMUX or similar equipment.
