1 × X.21 / V.35 / RS449
with 1 × RS366 Call Control up to 2 Mbps
Note the following:
V.10 (RS423).
For balanced signals a
0 = low voltage
, is defined as terminal
A positive with respect to terminal B.
For unbalanced signals a
0 = low volt-
age
, is defined as terminal positive
with respect to GND. Cable length
for
Leased Line Control
should not
exceed 20 m.
RS 366.
All balanced inputs and
outputs (A and B) use balanced line
signals according to V.11 (RS 422),
while single ended signals are in
accordance with V.10 (RS423). The
0 = low voltage
definitions are the
same as for V.10 above. Max cable
length, as for V.10 above.
X.21.
Signals are as for RS 366 above.
Cable length should not exceed 50 m.
