The CAS Multiframe structure is of variable length (in multiples of 8 frames), and this feature lends itself
to providing timeslot ID Maintenance for `Odd value of N`, ie values which the fixed length TS32 multiframe
cannot accommodate. This is an efficient use of the overhead as when not sending signalling information
15 out of every 16 TS16/TS48 locations are still available for high rate ESC, even when the CAS
multiframe is required to support `Odd values of N` or Robbed Bit Signalling.

+ N=32 is a special case normally handled as unframed 2048kbps (ie no Drop/Insert) or 1920/1984kbps (D/I with N=30/31)
