Setting a trunk clock quality setting

About this task

Procedure

1. Start Manager and connect to the B5800 Branch Gateway system.

2. In the left navigation pane, click Line.

3. For each digital line, do the following:

a) Select the line.

b) On the Line tab, select whether that trunk should provide the clock source for

the network or whether the trunk is unsuitable.

Note:

For E1R2 trunks the Clock Quality setting is on the Advanced tab

4. Ensure that only one trunk is set to Network. This should preferably be a direct

digital trunk to the central office exchange.

5. Set one other trunk to Fallback in case the selected network trunk connection is

lost.

Note:

If possible this should be a trunk from a different provider since that reduces the

chances of both sources failing at the same time.

6. Ensure that all other digital trunks are set as Unsuitable.

7. Select File > Save Configuration.

Setting the trunk prefixes

About this task

Where a prefix has been implemented for outgoing calls, that same prefix needs to be added

to trunk settings. The prefix is then used as follows:

• On incoming calls the prefix is added to any incoming ICLID received with the call. That

allows the ICLID to be used by B5800 Branch Gateway phones and applications to make

return calls.

• On outgoing calls, the short codes used to route the call to a trunk must remove the dialing

prefix.
