1. The NSVC is differentiated by the data link control identifier (DLCI).
2. An NSVC is carried on a bearer channel (BC) of an E1/T1. A BC can carry several NSVCs. An NSVC belongs to only one BC and only one NSE, whereas an NSE can correspond to several NSVCs.
3. A permanent virtual connection (PVC) is uniquely identified in a BSC by four parameters: Subrack No., Slot No., BC Identifier, and Data Link Connection Identifier. A BC supports up to 195 PVCs and a BSC supports up to 1024 PVCs.
| ID | Name | Description |
|---|---|---|
| NSVCI | NSVC Identifier | Meaning:NSVC Identifier Value range:0~65534 Explanation: This parameter specifies the NSVC Identifier (NSVCI). The NSVCI is unique in one NES. The number of NS-VCs configured on a BC depends on the number of timeslots occupied by the BC. Huawei recommends that the number of NS-VCs configured meet the following requirement: 10 kbit/s<=(number of timeslots occupied by BC x 64 kbit/s) / number of NS-VCs configured on BC NS-VC<=100 kbit/s. Default value:None |
| NSEI | NSE Identifier | Meaning:NSE Identifier Value range:0~65534 Explanation: This parameter specifies the NSE index. Default value:None |
| SRN | Subrack No. | Meaning:Subrack No. Value range:0~11 Explanation: This parameter specifies the number of the subrack that holds the GEPUG. Default value:None |
| SN | Slot No. | Meaning:Slot No. Value range:0~27 Explanation: This parameter specifies the number of the slot in which the GEPUG is located. Default value:None |
| BCID | BC Identifier | Meaning:BC Identifier Value range:0~255 Explanation: This parameter specifies the bearer channel ID. Default value:None |
| DLCI | Data Link Connection Identifier | Meaning:Data Link Connection Identifier Value range:16~1007 Explanation: This parameter specifies the DLCI value. The value range of this parameter depends on DLCIType. If DLCIType is set to 1, the DLCI value ranges from 16 to 1007. Default value:None |
