5. Configuration Using the NMS
Parameter | Description |
|
|
VPI/VCI Detect Setting | Specify the port behavior with regard to VPI/VCI |
| detection: |
| On – The DSLAM will monitor the line to determine |
| the VPI and VCI settings of the remote ADSL |
| modem and set itself accordingly. If no ATM cells |
| are detected (at any VPI/VCI setting), the port will |
| default to VPI 0 and VCI 35. |
| Off – The port will use the default setting of VPI |
| and VCI (0/35 if not changed by the setting of VPI |
| and VCI, below), or lock in the VPI/VCI already |
| discovered while VPI/VCI detection was On. |
|
|
Data Rate Setting | If you have selected a Port Mode of Fixed or Fixed |
| Adaptive, specify the maximum upstream and |
| downstream rates, in bps. |
|
|
Filter IP Address Settings | Specify up to four IP address ranges. Packets are |
| accepted from source IP addresses in the ranges |
| specified. |
|
|
Protocol Setting | Click in the check box to enable Protocol Setting |
| detection. Select Allow Selected and specify up to four |
| Ethertypes allowed on the ports. |
|
|
DHCP Option 82 | Specify whether DHCP Option 82 is enabled, and if it |
| is, whether packets are identified by IP address or |
| circuit ID. This identifier is added to packets to let your |
| DHCP Server recognize which DSLAM port an IP |
| address request is coming from, thereby allowing the |
| DHCP Server to limit the number of IP addresses |
| assigned per port. |
|
|
VPI and VCI | Specify a default VPI and VCI if VPI/VCI Detect |
| Setting (above) is Off. |
|
|
Frame Type | Specify whether the ports use Logical Link Control |
| (LLC) or Virtual Channel Multiplexing (VCM) bridged |
| encapsulation. These are defined in RFC 1483. |
|
|
Standard Mode | Specify the ports’ DSL mode. |
