DDM Network
Adapter
Connections
The DDM network adapter 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. Connections to Switched 56 and
ISDN networks are made, using a multiplexer, terminal adapter, IMUX or similar equipment.

Quad BRI Network
Adapter TA
Connections
The Quad BRI network adapter supports ISDN BRI networks. It requires the S/T interface from a BRI
NT1 device in an ISDN network. The board includes an IMUX, enabling you to achieve higher line
rates by connecting up to four BRI lines. Each BRI line requires an NT1 interface.
The NT1 interface may be provided by the ISDN service provider. With PBX systems, the NT1
interface is a component of the system.
