link cable
type
Sets the cable connected to this interface. The options are V.36and the
following DCE and DTE types: RS-232, V.35,and X.21.
A DTE cable is used when you are attaching the router to some type of
DCE device (for example, a modem or a DSU/CSU).
A DCE cable is used when the router is acting as the DCE and providing
the clocking for direct attachment.
link clocking
internal
or
external
Configures the SDLC link’s clocking. Toconnect to a modem or DSU, set
clocking external. Toconnect directly to another DTE device, use a DCE
cable, set the clocking to internal, and configure the clock speed. For
internal clocking, you must set the line speed in the range 2400 to 2048000
bits per second.
link duplex
full
or
half
Configures the SDLC line for
full-duplex
or
half-duplex
signalling.
Half-duplex
means that the 2210 raises RTS and expects to see CTS
before it will transmit data.
Full-duplex
means that the 2210 does not wait
for CTS to be raised before is transmits data.
Note: The duplex type does not control how SDLC operates at the SDLC
protocol level. The 2210 only supports two-way alternating mode
which is sometimes also referred to as SDLC half-duplex.
link encoding
nrz
or
nrzi
Configures the SDLC transmission encoding scheme as NRZ (Non-Return
to Zero) or NRZI (Non-Return to Zero Inverted). NRZ is the default.
link frame-size
Configures the maximum size of the frames that can be transmitted and
received on the data link. Valid entries are shown inTable 70 on page 546.
