The DDM-2000 OC-3 Multiplexer uses the E1 byte in the SONET overhead and
provides a 64 kb/s complementary metal oxide semiconductor (CMOS) or
transistor-transistor logic (TTL) compatible interface to an external order wire shelf
to provide point-to-point voice communication between DDM-2000 OC-3 systems.
If the DDM-2000 OC-3 Multiplexer is using R8.1 or R9.1, a proprietary MUX order
wire capability is available for use in
MegaStar 2000. The MUX order wire mode
provides access to the E1, E2, and F1 SONET overhead bytes in a proprietary
1.544 Mb/s data stream for use with the Harris-Farinon mini-CSU equipment.
The DDM-2000 OC-3 Multiplexer system has been tested with the DANTEL
