Bit 6: T1E1 Mode (T1E1). This bit determines if the IMUX operation is for T1 or E1 Mode.
Bit 5: Receive Enable (RXE). If this bit is set to 1, data will be received from the Serial Interface and passed to the
packet processor. If equal to 0, no data will be sent to the packet processor.
Bit 4: SEND Enable (SENDE). If this bit is set to 1, the data will be transmitted on the Serial Interface. If equal to 0,
data is blocked.
Bit 3: Link 4 (L4). If this bit is set to 1, link number four is participating in the communication. If this bit is equal to
0, the link does not participate.
Bit 2: Link 3 (L3). If this bit is set to 1, link number three is participating in the communication. If this bit is equal to
0, the link does not participate.
Bit 1: Link 2 (L2). If this bit is set to 1, link number two is participating in the communication. If this bit is equal to 0,
the link does not participate.
Bit 0: Link 1 (L1.) If this bit is set to 1, link number one is participating in the communication. If this bit is equal to 0,
