NRZI Data Encoding
[1,0]
I-NRZI
O-NRZ
This is the electronic signaling technique that is used for data transmission. See the
glossary for a definition of NRZI. This option must match the definition at the
SNA host.
Permanent RTS (Request to Send)
[1,0]
Line Speed
Line Type
I-The 3708 leaves RTS active at all times. Only use this option for a full
duplex point-to-point line (the 3708 is the only secondary control unit on the
line).
O-The 3708 raises RTS only when transmit is requested (the 3708 is on a
multidrop line).
[00 - 14]
OO-Extemal clocking
01-110 bps
02-150 bps
03-200 bps
04-300 bps
05-600 bps
06-1200 bps
07-1800 bps
08-2400 bps
09-3600 bps
10-4800 bps
11-7200 bps
12-9600 bps
13-14400 bps
14-19200 bps
Note: Clocking must be provided by either the 3708 or by a modem or a directly
connected host. Clocking must not be provided by both the 3708 and by the modem
or host. If the host or modem provides a clocking signal, you must define 00 for· the
upstream line speed. Use the values 01 through 14 only if you want the 3708 to
provide clocking. See Chapter 10, "Planning for Cables" for cable configuration
examples and additional information on host clocking requirements.
[D, L]
D-If the 3708 is directly connected to the SNA host (via a 3708 DTE cable, a
host DTE direct connect cable, or a null modem or modem eliminator, see
Chapter 10, "Planning for Cables"), you should define D for the host's line
type.
L-If the 3708 is connected to the SNA host using modems, you should define L
for the host's line type.
