"MNGT" Interface:
Port
V.11 synchronous (differential) interconnection possible with other SAGEM
equipment ADR155C, FOT 155C, through serial synchronous links used in
codirectional mode at 64 kbit/s or master contra-directional mode (rate
defined by the ADR 155C)
Bit rate
64 kbit/s,
Connector
Female 9-way HE5.

RXPB
(+)
2
RXPA
(-)
Input for data received over the P interface and sampled on the
rising edge of receive clock RXCLKP (B-A)
7
TXPB
(+)
3
TXPA
(-)
Output for data sent over the P interface on the falling edge of
transmit clock TXCLKP (B-A)
8
TXCLKPB
(+)
4
TXCLKPA
(-)
Output for transmit clock; in codirectional mode, the transmit clock
timing is derived from the equipment's internal timing

RXCLKPA
(-)
Receive clock input
*In slave contradirectional mode (coming) TXCLK signals are inputs.
