10. Add virtual trunks

Avaya suggests there is no reason for administrators to access the CS1000 CLI except for troubleshooting and disaster recovery. Therefore, we're going to do the next steps purly from within Element Manager, and in the process, try to get familiar with the EM command layout and menu structure.

Perform initial ESN block configuration:

Navigate to Dialing and Numbering Plans/Electronic Switched Network.
Inside the Network Control & Services section:

Click on ESN Access Codes and Basic Parameters.

Modify the CDB to allow use of ISDN trunks:

Navigate to Customers.

Under General Properties:

Click once again on ISDN and ESN Networking. Under Calling Line Identification:

Add virtual loop:

Navigate to System/Core Equipment/Superloops.

Add a D-Channel:

Navigate to Routes and Trunks/D-Channels.

Add the VTRK routes:

Navigate to Routes and Trunks/Routes and Trunks.

Add virtual trunks:

Next to the route click Add Trunk.

Under Basic Configuration:

Under Advanced Trunk Configurations:

One DCIP DCH works for both SIP and H.323 virtual trunks. The DCH assigns the appropriate channel for the call by using a Channel ID (CHID). For this reason the CHID must be unique regardless of which route the trunk is in. Using the example above, if the H.323 trunks are built first, and 30 are built, the CHID of the first SIP trunk must be 31. If there are 10 SIP trunks they will have CHIDs 31 through 40. If later additional H.323 trunks are added to the system, the first additional trunk will have CHID 41.

Check to see that the virtual trunks are registered. From LD 117 a STAT SERV will tell you if there are any virtual trunks registered. In LD 96 the command STAT DCH will tell you if the DCH is active and established. Via EM you can see the virtual trunks with the vtrkShow command. Also in EM you can see the DCH status from two places, System/Maintenance and Routes and Trunks/D-Channels.

Stat virtual trunks via EM:

From System/IP Network/Maintenance and Reports click GEN CMD.
From Group choose Vtrk.
From Command choose vtrkShow.
In the Protocol field enter h323 or sip.

In the VTRK Summary look for VTRK status : Active, Master status : On, Channels Idle : 10, or whatever number of channels exist.

Stat D-Channels via EM:

From Routes and Trunks/D-Channels click D-Channel Diagnostics (LD96).
Click Submit on the first line, Status for D-Channel (STAT DCH).

Add the MG Conference and TDS loops:

Each Media Gateway (MGC) requires a Conference (MGCONF) and TDS (MGTDS) loop.

Navigate to System/Core Equipment/Loops.

Back on the Loops page, use the dropdown box to select MG

Note in the image below that the new loops come up disabled.

To enable the TDS loops, navigate to System/Maintenance.

Follow the same procedures for LD 38 - Conference Circuit. After the Conference loop is built, navigate back to the loop page and see that both have a Current status of Enabled.

To print, PRT CEQU in LD 22. MG Conference and TDS loops can be built on any loop, for example:

         100  000  0   MGC
         102  000  1   MGC
         104  004  0   MGC
         106  004  1   MGC
         108  008  0   MGC
         110  008  1   MGC
         101  000  0   30    MGC
         103  000  1   30    MGC
         105  004  0   30    MGC
         107  004  1   30    MGC
         109  008  0   30    MGC
         111  008  1   30    MGC

Add Digitone Receivers:

Each Media Gateway (MGC) requires eight (8) Digitone Receivers (DTRs) built on virtual card 15.

Navigate to System/Core Equipment/Tone Senders and Detectors.
