Consolidated T1 Access of DDS Circuits
The following example illustrates how to use the OCU-DP APM to reduce facility
costs associated with point-to-point 56/64K connections by consolidating these
lines into a single T1 facility. The T1 Access Muxes shown in this application
could also be used to support both voice and high-speed data.
Typically, T1 Access Muxes are placed at concentration points where a single T1
line is less costly than multiple (typically four or five) 56K lines. If DSUs are left at
both ends of the circuit, proprietary DSU Network Management Systems can be
used. Or, circuits associated with remote DSUs can be terminated directly on a
Sync Data APM at the Data Center to eliminate Data Center DSUs.
The OCU-DP APM does not support subrate DDS rates. Subrate applications can
be supported by installing a Paradyne 3610 or similar device configured for
56/64K line speed.
