Adtran ATLAS 550 T1 PRI Network Module

An ATLAS 550 module providing a single interface which can be configured for T1 or PRI.

ATLAS 550 Modules
Cross-Connect System (DACS), and a Frame Relay Switch. These modules provide either one, two, or four ports, each of which can be independently configured to operate in T1 (DS-1 or DSX-1) or Primary Rate ISDN (PRI) modes.

The ATLAS 550 can perform T1 or PRI conversion, translating between the robbedbit signaling presented in a channelized T1 circuit and the D-channel signaling of a PRI circuit. When using the T1/PRI modules, ATLAS can also operate in a DACS mode supporting DSO time slot interchange and DSO grooming while preserving robbed bit signaling. ATLAS can be fully populated with T1/PRI modules to support a pure DACSing application of 18 T1/FT1 circuits or 18 PRIs.

T1/PRI modules can be used to interface with both the public network and end-user equipment. The single T1/PRI module can only be used in the Network Interface slot, while the Dual and Quad T1/PRI modules can be used in any of the four User slots of the ATLAS 550.
