Introduction
Description
Codec 6000 MXP
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 voltage, 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.
