Includes services at the MUX entity level and at the specific DLC level.
MUX Entity Level services (channel 0):
Test Service used to test the communication link between two MUX entities.
Specific DLC Level services (all DLC except 0):
1. A specific DLC HW modem status is reflected by logical (SW) means. A Modem
Status Command (MSC) is used to control specific DLC modem signals, as a
substitute for the HW lines in PREMUX. Initial values are expected to mirror the HW
values in PREMUX.
