Configure DS0 ports for GR-57 interface

Host DS0 ports provide a GR-57 switch interface for DS0 services. Remote DS0 ports provide a subscriber interface for DS0 services. You configure the host ports for the type of service connected to the switch, and the remote ports for the type of DS0 service delivered.
Configuring host and remote DS0 ports services
Ports on host and remote DS0 equipment can be configured for many DS0 switched services:
 
  • POTS service for ports on HPOTS-24 and HU2W-24 host cards and RPOTS-24 and RU2W-24 remote cards.

  • Coin service on the first four ports of the HU2W-24 host card and the first four ports of the RU2W-24 remote card. Set the GSFN parameter to 2COIN.

  • UVG service on DS0 ports on the HPOTS-24 and HU2W-24 host cards and RPOTS-24 and RU2W-24 remote cards. Set the GSFN parameter to a UVG service type.

  • EBS service on the HEBS-12 host card and REBS-12 remote card. Port parameters on an HEBS-12 and REBS-12 cards are set for EBS service.

Procedure to set DS0 port parameters
The DS0 port parameter illustrations in step 5 show parameter values for POTS service. Choose different values to configure the port for other DS0 services.
 
Step Action
1. On the Navigation Tree, click a shelf containing DS0 ports.
2. On the Filter list, click Facility, then click DS0 Facility to show all DS0 ports from the selected shelf in the Work Area.
3. On the Provisioning page, click the first DS0 port to configure then press shift and click the last DS0 port to select a range of ports to configure.
4. On the provisioning page set the following DS0 parameters:
  1. In the Primary Service State list, click Out of Service to place the port out of service.
  2. In the General Signaling Function list, click a signal type.
  3. In the Receive Transmission Level Point list, click a decibel value.
  4. In the Transmit Transmission Level Point list, click a decibel value.
  5. In the Impedance list, click an impedance of 600 or 900 ohms.
5. On the toolbar, click Apply, then click OK to save the DS0 port configuration.
 
6. On the Provisioning page, select the same range of ports to configure as selected in step 3.
7. In the Primary Service State list, click In Service to place the port back in service.
8. On the toolbar, click Apply, then click OK to put the DS0 port back into service.
