Configuring A Ct3 Interface - HP HSR6800 Configuration Manual

Task
Display the state information of a
CE3 interface.
Display the configuration and state
of a serial interface formed on a
CE3 interface.
Clear the controller counter of a
CE3 interface.
Shut down a CE3 interface.
Bring up a CE3 interface.
Shut down an E1 line.
Bring up an E1 line.
Shutting down/bringing up a CE3 interface also shuts down/brings up the E1 lines demultiplexed from
the CE3 interface, the serial interfaces formed by the E1 lines, and the serial interfaces created on E1
lines by means of timeslot bundling.
Shutting down/bringing up an E1 line also shuts down/brings up the serial interface formed by it and
the serial interface created on it by means of timeslot bundling.
To shut down/bring up only a serial interface formed by E3 or E1 lines, or by timeslot bundling on an E1
line, run the shutdown/undo shutdown command in the view of the corresponding serial interface.

Configuring a CT3 interface

Both T3 and T1 belong to the T-carrier system promoted by ANSI. T3 uses the digital signal level DS-3
and operates at 44.736 Mbps.
CT3 interfaces support two operating modes: T3 (unchannelized) and CT3 (channelized).
In T3 mode, a CT3 interface is a synchronous serial interface with 44.736 Mbps of data bandwidth,
•
on which no timeslots are divided.
In CT3 mode, a CT3 interface can be demultiplexed into 28 channels of T1 signals. Each T1 line
•
can be divided into 24 timeslots numbered 1 through 24. Different from E1, each line on a T1
interface can operate at either 64 kbps or 56 kbps. Therefore, the number of logical lines that can
be created on a CT3 interface in CT3 mode is either M × 1.536 Mbps (where M ranges from 1 to
28) or N × 56 kbps or N x 64 kbps (where N ranges from 1 to 300).
When a T1 line is working in unframed (T1) mode, the system automatically creates a serial interface
named serial number/line-number:0 for it. This interface operates at 1544 kbps and is logically
equivalent to a synchronous serial interface where you can make other configurations.
