Proper GR-303 provisioning to a Class 5 switch requires that a primary DS1 line and a secondary DS1 line be established. Prior to provisioning, users should determine which DS1 lines from the Class 5 switch will serve as the primary and secondary DS1 lines. Each interface group can have up to 28 DS1s.
The following procedure assigns call reference values (CRVs) to a GR-303 interface group.
Step 1 Starting from the node view, select Objects > Interface Group from the menu bar. (See Figure 7-1.)
Step 2 EMS launches the interface group provisioning window. (See Figure 7-2.) The grayed out GR-303 Interface Group tab shows that you are in the GR-303 provisioning screen.
Step 3 Set the following GR-303 parameters:
Step 4 Click Apply to provision CRVs for the interface group.
At least two DS1 lines (the primary and secondary DS1) must be provisioned for GR-303. Use the following procedure to provision embedded operation channel (EOC) and timeslot management channel (TOC) lines:
Step 1 Starting from node view, double-click the facility (line) to be provisioned. EMS launches the line provisioning window. (See Figure 7-3.)
Step 2 In the line provisioning window, set the following parameters:
Step 3 Click Apply to provision the DS1 line.
Step 4 Repeat this procedure until all DS1 lines are assigned to the GR-303 interface group.
GR-303 provides dynamic cross connects. This type of concentration allows one DS1 to serve more than 24 subscribers. Instead of creating traditional cross connections, GR-303 provisioning is performed by assigning call reference values (CRV) to analog lines. CRVs are used to build translation tables on the Class 5 switch that map remote analog connections to internal circuits at the switch.
To begin GR-303 provisioning, launch the node view of a specific node. Double-click on a specific analog line to launch the line provisioning window. (See Figure 7-4.)
From the line provisioning window, the following parameters must be defined:
Click Apply to complete GR-303 provisioning for the line. Repeat this procedure to provision additional GR-303 lines.
To change or reset the Call Reference Value (CRV) of an analog line, complete the following steps from the analog line provisioning window:
Step 1 Change the Interface Group Type of each analog line to be reset to TR-008.
Step 2 Click Apply to complete the change.
Step 3 Change the Interface Group Type of the line back to GR-303, and reassign the CRV as desired. The appropriate Interface Group ID must also be specified.
Step 4 Click Apply to complete the change.
This procedure must be followed to change the CRV for any analog line while performing GR-303 provisioning from the analog line provisioning window.
Intra-node GR-303 provisioning can also be performed in batch mode (that is, multiple POTS lines and RPOTS cards can be provisioned at one time).
Step 1 To begin batch CRV provisioning, select Objects > CRV Batch Provisioning from the node view of the node to be provisioned. (See Figure 7-5.) The grayed out Local CRV tab indicates that you are at the local CRV provisioning window.
Step 2 From the CRV batch provisioning window, select the Card Type to be provisioned. Upon selecting a card type, EMS will display the applicable card numbers in the Card List display.
Step 3 In the card list display, highlight the cards to be provisioned. Click the right arrow icon to move the selected cards to the Selected list.
Step 4 Select the appropriate Interface Group ID (from 1 to 4), and click the List button to show card, line, and interface group information in the Result List display.
Step 5 To assign CRVs, enter starting and ending values in the CRV Range From and CRV Range To fields.
Step 6 Highlight the lines to be provisioned in the result list, and click Assign to begin the CRV batch provisioning process. EMS displays the assigned CRVs in the result list. (See Figure 7-7.)
To change or reset the Call Reference Value (CRV) of POTS lines while provisioning in CRV batch mode (CRV Batch Provisioning screen):
Step 1 Select Objects > CRV Batch Provisioning from the node view of the node to be provisioned. Click the CRV Lists tab to launch the CRV list window. (See Figure 7-8.)
Step 2 Set the following parameters in the CRV list window:
Step 3 Click Show to display the CRV information, including card and line numbers, in the CRV List. (See Figure 7-9.)
Step 4 In the CRV list display, highlight the CRVs to be deleted. Click Delete to delete the CRVs. EMS confirms the deletion by removing the selected CRVs from the CRV list.
To set the DSX1 line that is connected to the Class 5 Switch for TR-008 operation, use the settings listed below:
EMS allows users to provision POTS lines in batch mode for GR-303.
Step 1 Select Applications > CRV Batch Provisioning from the inter node cross connect display menu. EMS launches the inter node CRV batch provision screen. (See Figure 7-10.)
Step 2 Select an Interface Group ID to be assigned (from 1 to 4).
Step 3 Set the Allocated Number of CRVs to the number of CRVs for the selected interface group.
Step 4 Click Apply to provision the interface group.
Step 5 Click Inter-Node CRV Batch Assignment in the function bar. EMS displays the inter node CRV batch assignment window. (See Figure 7-11.)
Step 6 From the inter node CRV batch provision window, the following parameters must be defined:
After the appropriate cards have been moved to the Selected list, click the List button to display card and line information. (See Figure 7-12.)
Step 7 Set the following fields for remote CRV batch provisioning:
Step 8 Click Assign to provision the CRVs.
To change or reset the CRVs of analog lines:
Step 1 Select CRV Batch Reset in the function bar. EMS displays the CRV batch reset window. (See Figure 7-13.)
Step 2 Set the following parameters:
