I believe you are wrong, but this may be one of those "it depends" type
of things. SPIDs are layer 2 communication between the ISDN TE and the
switch, related to the actual raw B channel. If the switch requires a
spid for one channel, it will require it for the other as well. Note
that the real world may vary from a simulator and from the specific lab
environment.
