14.3.1
D&I Primary Data Interfaces
When configured for D&I operation, multiplexing/demultiplexing follows the IBS satellite frame
structure and ESC features, but with the following changes:
•
Accepts and outputs primary data through the G.703 connectors.
•
The data rate must be at T1 or E1 rates only. This includes additional links for Drop Data
Out and Insert Data In.
•
Clock recovery, dejitter, and encoding/decoding are performed as before.
14.3.2
D&I Framing
The IBS satellite framing/deframing is applied only to selected time slots of the data’s G.704
terrestrial structure.
