Setting up digital trunks
Any of the common trunks, except for PCOL trunks, can be analog or digital.
(PCOL trunks can only be analog.) Administering a digital trunk group is very
similar to administering its analog counterpart, but digital trunks must connect to a
DS1 circuit pack and this circuit pack must be administered separately. The
example in this section shows you how to do this.

In most cases, Lucent recommends leaving the default settings in fields that aren’t

CAUTION:
If enhanced DS1 administration is not enabled, you cannot make changes to
the DS1 Circuit Pack form before you remove related member translations of
all trunks from the trunk group. Refer to

Before you can administer a digital trunk group, you must have one or more
circuit packs that support DS1 with enough open ports to handle the number of
trunks you need to add. To find out what circuit packs you need, refer to the
DEFINITY ECS System Description.
