Functional Description
3.1.2.2
Structured CES Mode
A port is programmed for the Structured T1/E1 Nx64 kbit/s Basic Service (Structured
CES) via the port configuration register “pcfN” (“p_ces” = 0).
The structured circuit emulation service is intended to carry N of the 24 (T1) or 32 (E1)
timeslots across the ATM network.
An emulated Nx64 kbit/s circuit will be referred to as a channel throughout this
document. It is possible that several channels share the same physical interface port.
In structured CES mode neither SRTS nor ACM clock recovery is possible.
