*Channel 16 (time slot 6) can be used for the Serial CES service without affecting E1 signaling. The E1 signaling information is extracted from the
CBR interface data stream prior to multiplexing it with the Serial interface stream. Therefore, replacing channel 16 (time slot 16) with Serial
interface data will not affect the assembly or reassembly of the signaling data in the CES data stream.
**The signaling information in the channel is automatically extracted in this mode and assembled in the signaling substructure of the ATM
payload. Including channel 16 in the CBR interface data stream would duplicate the data transmitted in the signaling substructure and is
therefore not needed.
***An Unstructured T1 CES service is not compatible with a Serial interface CES service because the Serial interface does not support a 1.544
MHz clock rate. However, you may use a Basic T1 CES service and allocate all 24 channels to the Serial interface CES service resulting in a
1.536 MHz clock rate.
HDLC/PPP Service
This service has no configurable parameters.
