Description: This attribute is applicable to E1 interfaces only. It specifies the mapping scheme between channel numbers (identified in Layer 3 messages) and timeslot numbers on the E1 link. When the attribute value is skip16, channel numbers map directly to actual E1 timeslots; therefore only channel numbers 1 - 15 and 17 - 31 are expected. When the value is contiguous, channel numbers from 1 - 30 are expected, and the following mapping is used: channels 1 - 15 are mapped to timeslots 1 - 15, and channels 16 - 30 are mapped to timeslots 17 - 31. On T1 interfaces, channel numbers are always expected in the range 1 - 23.

What is sigChanEQsigE1ChannelNumbers?

This applies only to E1 interfaces and selects the channel-to-timeslot mapping scheme: 'skip16(1)' (default, channels 1-15 and 17-31 map directly to E1 timeslots, skipping timeslot 16) or 'contiguous(2)' (channels 1-30 map with 16-30 shifted onto timeslots 17-31); admins must match this to how the connected PBX numbers its channels to avoid a channel-numbering mismatch.
