Description: Indicates types of calls to assign to this resource
for this customer profile.

This object is a bit map, with each bit representing
a different call type as identified below.
A 1-bit indicates that call type is supported.
A 0-bit indicates that call type is not supported.

Bit 0   - Digital
Bit 1   - Speech
Bit 2   - V.110
Bit 3   - V.120

Setting all defined bits to 1 would result in this
resource being available for all calls.
Setting all defined bits to zero would result no
calls being assigned to this resource.

Q.931 specifies Bearer Capability associated with calls.
RFC 2127, ISDN MIB defines the object isdnBearInfoType,
combining Q.931 bearer capability information
transfer capability and user rate.

The correlation between Q.931 information transfer capability
and call types is:
  Call Type        Q.931
  ---------        -----
  digital = {unrestricted digital, restricted digital}
  speech  = {speech, 3.1kHz audio, 7kHz audio}
  v110    = {Anything with V.110 User Info Layer}
  v120    = {Anything with V.120 User Info Layer}

The Q.931 user info layer values of V.110 or V.120 override
all other fields in determining resource manager call types.

The remaining Q.931 transfer capabilities are not currently
supported by resource manager.

The mapping for RFC2127 is:
  Call Type        RFC2127
  ---------        -------
  digital = {unrestrictedDigital,unrestrictedDigital56,
             restrictedDigital}
  speech  = {speech, audio31, audio7}
  v110    = {Not represented in RFC2127}
  v120    = {Not represented in RFC2127}

The remaining RFC2127 values are not currently
supported by resource manager.
