The parameters in this group define the timing and signaling values for a trunk. The field-level parameters in this group define signaling levels, transmission speeds, and cadences for the trunk.
The trunk interface parameters must be defined once for each pack. The values then apply to all channels assigned to that trunk. Up to 16 T1 or E1 trunk interfaces can exist.
To make new parameter values effective, disable then enable the pack.
Some predefined trunk interfaces are supplied as templates (see Trunk interface templates). You cannot edit the values in the templates. You must copy the templates and paste them onto numbered trunk interfaces (1, 2, 3, and so on).
