T1 Mode:
E1 Mode:
In the ESF framing mode, there can be up to four signaling bits per channel (A, B, C, and D). In the D4 framing
mode, there are only two signaling bits per channel (A and B). In the D4 framing mode, the framer will repeat the A
and B signaling data in the C and D bit locations. Therefore, when the framer is operated in D4 framing mode, the
user will need to retrieve the signaling bits every 1.5ms as opposed to 3ms for ESF mode. The receive-signaling
registers are frozen and not updated during a loss of sync condition. They will contain the most recent signaling
information before the “OOF” occurred.
