Subject: [Megaco] question about atm sdp(RFC 3108)

hi, all

atm sdp address following atm applications :
"
1. Applications in which a new SVC is set-up for each service connection. 
   These SVCs could be AAL1 or AAL5 SVCs or single-cid AAL2 SVC.
2. Applications in which existing path resources are assigned to service
connections.
   These resources could be :
   * AAL1/AAL5 PVCs, SPVCs or cached SVCs,
   * AAL2 signle-CID PVCs, SPVCs or cached SVCs,
   * CIDs within AAL2 SVCs/PVCs/SPVCs that multiplex multiple CIDs,
   * subchannels (identified by CIDs) within AAL1 or AAL2 SVCs/PVCs/SPVCs

" (RFC3108, page 4)

does single-cid AAL2 SVC refer to AAL2 SVC which has a single channel?
is it impossible to make multiple-channel AAL2 SVC using ATM SDP?

thanks in advance.
