Channel

-

Displays the channels occupied by PDH services.

Channel Name

-

Sets or displays the name of each channel.

Laser Switch

On, Off

Default: on

Setting the laser switch.

Branch loopback

Unlooped loopbacks, inner loopbacks

Default: no loopback

Channel Impedance

-

The impedance of the display channel is determined by the actual condition of the tributary unit.

Business Loading Instructions

Load, unload < /p>

Default: load

Display or set the service loading status of the corresponding channel.

• Set as "loaded" detects alarms for this channel.
• Set as "Do not load " when not detecting alarms for that channel.

For the channel that has no service running on the branch unit If you want to block all the alarms of this channel, you should set the service loading indication of this channel as "Not loaded". The channel with business operation, the corresponding channel is set to "load".

Re-timing method

Normal mode, branching clock re-timing mode, cross clock re-timing mode

Default value: Normal way

Displays or sets the retiming method for the channel.

The retiming function is to synthesize the timing reference signals from the digital synchronization network and service data signals are synthesized together and sent to the customer equipment, a method to reduce the signal output jitter. This is a way to synthesize a good timing reference signal with the business code stream signal so that the business code stream can pass the timing reference signal well.

Re-timing method is supported only by E1 port.

• Set to "Normal mode" when set to "normal mode", it means that the re timing function.
• Set to "Branch clock re Timing Method" when it indicates that the retiming function is used by tracking the uplink branch clock.
• Set to "Cross-clock re Timing Method" when it indicates that the retiming function is used by tracking the cross-clock method.

It is recommended to try to provide external clock to the device by using external clock , without using the retiming feature.

If you want to use re-timing, it is recommended to set the "Cross-clock retiming method".

Yardage

-

Channel Business Type

-

Displays the type of service for each channel of the tributary unit, related to the service actually transmitted by the channel.

Port Mode

2M optical transmission mode, C37.94 unframing mode

2M optical transmission mode, C37.94 deframing mode

Default: 2M optical transmission mode

Set the port mode of the single board.

C37.94 number of time slots

-

Set the number of time slots for C37.94.
