TS
Ports 1 through 4 can be set for any number of contiguous timeslots, up to 24 for T1 (DSX)
WAN and 32 for E1 (CEPT) WAN. For ports 5 through 128, these can set for a single DS0
only.

RIP Rx

setting it to off.The following are internally set defaults for RIP, they cannot be changed:
RIP Tx
Set each port to transmit RIP packets in v1 or v2 mode - or turn it off. v2 is the default.
SH
Enables or disables split horizon on Ethernet. Options are yes or no. Split-horizon route
advertisement is a method of preventing routing loops in distance-vector routing protocols
(such as RIP) by prohibiting a router from advertising a route back onto the interface from
which it was learned.
LINK ST
This display-only field shows the state of the LCP (Link Communications Protocol) internal
status. In order for PPP to properly initialize, the LCP negotiation between the near end and
far end must complete, and display an UP value. A DS1 circuit that is in-service at both ends,
will not be able to carry PPP traffic if the LCP link status is DOWN. If there is no
provisioning, or there is a communication issue to the IPR*4 card, then the default of n/a is
displayed.
