Note these requirements and recommendations:
Each RLP must have X.25 configured.
RIP is valid only if IP is already configured on the RLP.
SNMP will not work unless IP is also configured in the node. IP can be, but does
not have to be, on the same RLP.
IP, IPX, and SNMP should not be configured on more than one RLP each. (All
three can be configured on the same or different RLPs.)
To configure a protocol on a port, the protocol must first be configured on the
LP containing the port.
is the line coding technique used to carry clock signals.
is the frame format. G.704 is a CEPT standard, with a set value.
specifies (as configured) that the RLP will use all of the DS0 channels on the E1 line.
is the distance from the LP to the external T1/E1 device. G.703 is a CEPT standard,
with a set value.
is the clocking mode in which the LP runs:
disables (as configured) the generation of CRC-4 (polynomial X4 + X + 1).
is the mode of the CEPT interface.
is the setting of the national use bits in the non-frame alignment signal. National use
bits 1-5 correspond to data bits 4-8 in the non-frame alignment signal. National use
bits are reserved for use within a country. If the signal will cross an international
border, the national use bits should be
is the setting of bit 0, which is transmitted as the most significant bit of the frame
alignment signal when CRC-4 is disabled.
