4.Click Full Duplex or Loopback in the Channel Mode field. Full duplex is the normal mode of operation.

5.Click AMI or HDB3 in the E1 Encoding field to select the E1 encoding. Click Apply.

This setting must match the line encoding of the CSU/DSU at the other end of the point-to- point link.

6.Click E1 (channel 0 framing) or No Framing in the E1 Framing field to select the E1 Framing format.

Use E1 framing to select whether timeslot-0 is used for exchanging signaling data.

7.Click On or Off for the E1 CRC-4 Framing field.

Note

This option appears only if you have set the E1 Framing field to E1 (channel 0 framing).

This button chooses the framing format for timeslot-0. On means that CRC-multiframe format is used; the information is protected by CRC-4. Off means that doubleframe format is used. This setting must match the setting of the CSU/DSU at the other end of the link.

8.Click On or Off for the E1 timeslot-16 Framing. Click Apply.

Note

This option appears only if you set the E1 Framing field to E1 (channel 0 framing).

This value controls whether timeslot-16 is used in channel associated signaling (CAS). Setting this value to On means that timeslot-16 cannot be used as a data channel. See fractional settings on the Advanced E1 CSU/DSU Options page.

9.Click Frame Relay in the Encapsulation field. Click Apply.

10.Enter a number in the Keepalive text box to configure the frame relay keepalive interval. Click Apply.

This value sets the interval, in seconds, between keepalive protocol message transmissions. These messages are used periodically to test for an active remote system. The range is 0 to 255. The default is 10.

Note

This value must be identical to the keepalive value configured on the system at the other end of a point-to-point link, or the link state fluctuates.

11.Click DTE or DCE in the Interface Type field.
