SONET sub-channel syntax
Syntax examples
The NFM-P uses the following SONET syntax for the STS-1 sub-channel:
card slot/daughtercard/port.STS1-[STS3#].[STS1#]
DS3 channels from an STS-1 sub-channel use the following syntax:
slot/daughtercard/port.DS3-[STS3#].[STS1#]
DS1 channels from a DS3 channel use the following syntax:
slot/daughtercard/port.DS1-[STS3#].[STS1#].[DS1#]
E1 channels from a DS3 channel use the following syntax:
slot/daughtercard/port.DS1-[STS3#].[STS1#].[E1#]
VT15 or VT2 from a VT group use the following syntax:
slot/daughtercard/port.VTG#-[STS3#].[STS1#]
DS1 channels from a VT15 or VT2 use the following syntax:
slot/daughtercard/port.DS1-[STS3#].[STS1#].[VT15#] or [VT2#}.[VTG#].[DS1#]

Description |
Additional information |
---|---|---|
Channel 1/1/1.sts1-2.2 |
1/1/1 is the slot number/daughtercard number/port number 2 is the STS-3 number (1 to 4) .2 is the STS-1 number (1 to 3) |
The sts1 parameter is 2.2 which means that it is the fifth STS-1. There are four STS-3s for an OC-12 and each STS-3 has three STS-1s such that the fifth STS-1 is the second STS-1 of the second STS-3. |
Channel 1/1/1.ds3-2.2 |
.ds3-2 is the STS3 number (1 to 4) .2 identifies the STS-1 number (1 to 3) |
Identifies the DS3 channel and shows how the sts1 level acts as a place holder for the DS3 |
Channel 1/1/1.ds1 2.2.25 |
.ds1-2.2.25 identifies a DS1 channel (1 to 28) on the DS3 |
The DS1 is configured on the DS3. |
Channel 1/1/1.e1 2.2.21 |
.e1-2.2.21 identifies a E1 channel (1 to 21) on the DS3 |
The E1 is configured on the DS3. |
Channel 1/1/1.DS0Grp-2.2.20.5 |
.DS0Grp-2.2.20.5 identifies one of the DS0 channel groups: 1 to 28 for DS1; 2 to 32 for E1 |
The DS0 is configured on the DS1 or E1 channel. |
Channel 1/1/1.ds1 2.2.3.18 |
ds1 2.2.3.18 identifies a DS1 channel on the VT15 or VT2 payload, where 3 is the VT group. |
