The parameter represents the bit-rate of the TDM service
in multiples of the 'basic' 64 Kbit/s rate. It complements
the definition of cpwVcType used in CISCO-IETF-PW-MIB.
For structure-agnostic the following should be used:
a) Satop E1 - 32
b) Satop T1 emulation:
i) MUST be set to 24 in the basic emulation mode
ii) MUST be set to 25 for the 'Octet-aligned T1'
emulation mode
c) Satop E3 - 535
d) Satop T3 - 699
For all kinds of structure-aware emulation, this parameter
MUST be set to N where N is the number of DS0 channels
in the corresponding attachment circuit.
