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

used. This setting must match the setting of the CSU/DSU at the other end of the link.

fractional settings on the Advanced E1 CSU/DSU Options page.

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.
