5013 Circuit Switched Trunk Service With T1 Transport (NYNEX Region Specific)

Multiplexing - T1 Transport - 1.544 Mbps - Trunk Side

This provides the ESP with a digital 1.544 Mbps facility at their premises that
is then available to provide up to 24 Circuit Switched Trunk Basic Serving 
Arrangements.  When utilizing analog network terminations, the telephone company
will provide multiplex and/or channel bank equipment to multiplex 24 
transmission paths of a frequency bandwidth of approximately 300 to 3000 Hz into
a DS1 signal.  When utilizing digital network terminations, the telephone 
company will provide a DS1 signal in a D3/D4 format.  All service will be 
provided with individual transmission path bit stream supervisory signaling.

All circuit switched BSAs on a DS1 facility must be uniform in that they must 
all terminate in the same suitably equipped circuit switch.  When using analog 
network terminations, all of the individual 24 circuit switched BSAs must be of
the same equipment type (e.g., trunk circuit switched BSAs).
