name Function Description
Line output
This parameter is used to adjust the signal strength
，
Optional is
0/-7.5/-15/-22.5 dB
，
Default "0dB"
，
In general, you can use the default
value.
。
CRC Verify
Default not verified
。
This parameter must be negotiated with the peer
device.
。
<Channel mapping table> tag
Select the Channel Map Table tab
，
As shown in Figure 6-131
，
Channel maps can view and edit the
purpose of each channel
。
In some cases, the user divides the channels in E1/T1 into data channels and voice
channels
。
Figure 6-131 PCM Settings - Channel Mapping Table
In the case of E1
：

PRI
：
16 channels are dedicated signaling channels
。

SS7
：
You can use the 1 to 31 channel according to the peer negotiation.
。

Description
：
When the E1/T1 interface is connected
，
Both parties must be identical on the E1/T1 interface parameters.
，
Because both E1/T1 cannot have signal loss/frame out-of-synchronization/multiframe
out-of-synchronization/slip code conditions
，
Because the inconsistency of individual characteristic
parameters will cause data channel failure / error code / slip code / out of step, etc.
。
These characteristic
parameters are: impedance / frame / line coding / CRC check,The above parameters need to be negotiated
with the peer when docking.
