The TR-TSY-000008 Bellcore

TM

 standard (commonly referred to as TR-08) describes the 

generic requirements for interfacing between local digital switches and remote digital 
terminals via the SLC

 96 digital loop carrier system.

TR-08 has three operational modes. The Z-Plex supports Mode I:

Mode I is a non-concentrated, non-blocking configuration where each channel is 
assigned a dedicated DS0 time slot. 

Mode II is a concentrated configuration (allows blocking) with 48 channels sharing 
24 DS0 time slots. Time slots are assigned on a demand basis for the duration of the call. 

Mode III is a non-concentrated mode used for coin and D4 single-circuit channel banks.

The RT channel numbering scheme supported by the product is described in Bellcore 
publication TR-TSY-0000008.
