| Would the switch treat them as one trunk group because they are in one signaling group? The answer is yes and no, clear huh?
They are one trunk group as far as the vendor is concerned and to the extent that they are in the same signaling group the switch considers them one group (notice I say one group not one trunk group), but trunk groups can overlap signaling groups and vice versa.
You can have a trunk group with five T1s in it and five different signaling groups and the switch will treat that as one trunk group. For testing and measuring you are dealing with one trunk group that could have T1s from several vendors, it is still one trunk group to the switch.
Likewise you can have five trunk groups that each contain members of the same signaling group (remember that you can have more members in a signaling group than you can possibly fit in one trunk group) and the switch will treat that as five trunk groups. For testing and measuring you are dealing with five trunk groups even though they might be NFAS and being controlled by the same D channel from the vendor.
The relationship between trunk groups and signaling groups is not a straight one to one thing. If it were, you could not mix them. |
