There are additional factors to note regarding specific values of N and the 
NxDS0 service:
— N = 1 — this is considered a narrowband call and is treated as any 
other voice or narrowband-data (B-channel) call.
— N = 6 — if a trunk group is optioned for both H0 and N x DS0 
service, a 384-kbps call offered to that trunk group is treated as an 
H0 call and the H0...

To reduce glare probability, the network needs to be administered so both sides of 
the interface select channels from opposite ends of facilities. For example, on a 
23B+D trunk group, the user side could be administered to select B-channels 
starting at channel 23 while the network side would be administered to start 
selecting at channel 1. Using the same...
