Parameters
e1-number: Number of an E1 channel on the CPOS interface, in the range of 1 to 63.
Usage guidelines
So far, E1 channels on CPOS interfaces support two operating modes: clear channel (or unframed) and
channelized (or framed).
• In unframed mode, an E1 channel can form a 2.048 Mbps serial interface without timeslot division.
This interface uses the serial slot/port/e1-number:0 format.
• In framed mode, all timeslots except timeslot 0 on the E1 channel can be bundled arbitrarily to form
serial interfaces.
Examples
# Set E1 channel 3 on CPOS 1/0 to operate in unframed mode.
<Sysname> system-view
