5. Configure the clock source for the interface in the Clocking pull-down
menu.
• Select line if you want the interface to take its timing from the public
carrier's equipment.
• Select internal if you want the interface to provide the timing for the
connection.
• Select through if you have a module with more than one E1 or T1 port
and you want this interface to take its timing from the other interface.
(See Chapter 4: Configuring E1 and T1 Interfaces for more informa-
tion about clock sources and when to use the through setting.)
6. Set the frame format to match your service provider's settings:
• If you are configuring an E1 interface, use the pull-down menu to
select E1 or CRC4. E1 is the default setting.
• If you are configuring a T1 interface, click ESF or D4. ESF is the
default setting.
Select the TS16 box to enable TS16 signaling only if you are configuring the
G.703 interface for an E1 + G.703 module. For more information, see "E1 +
G.703 and T1 + DSX-1 Modules" on page 14-105.
7. Use the Coding pull-down menu to configure the coding to match your
service provider's settings:
• If you are configuring an E1 interface, use the pull-down menu to
select HDB3 or AMI. HDB3 is the default setting.
• If you are configuring a T1 interface, use the pull-down menu to select
B8ZS or AMI. B8ZS is the default setting.
8. If you are configuring a T1 interface, use the pull-down menu to set the
facility data link (FDL). The default setting is ANSI. You can also select
ATT or None.
9. If you are configuring an E1 interface, you can set the Sa4Tx-Bit to 0 or
1. The default setting is 0.
10. In the Data DS0s field, configure the channels for the connection. This
setting must match the channels configured on your service provider's
equipment, or the Data Link Layer protocol cannot establish a connection.
• If you are leasing the entire E1-carrier line, set the timeslots to 1 to 31.
• If you are leasing the entire T1-carrier line, set the timeslots to 1 to 24.
