Table 6-9 shows the main settings that you must configure for an E1, T1, or
serial interface that uses HDLC.

Explanation
• defines the number of channels
used for the E1 connection
• defines the line coding
• defines the frame format
• defines the clock source, or timing,
for the connection
• activates the interface
• defines the number of channels
used for the T1 connection
• defines the line coding
• defines the frame format
• defines the clock source, or timing,
for the connection
• sets the level of the transmit signal
• activates the interface
• configures the serial interface to
support the appropriate cable
• configures the serial interface to
take the clock from the transmit
signal, txclock, or from the receive
signal, rxclock
• activates the interface
