Sagem ADR 155C manual Mngt Interface, Polarity Comments

1 - INSTALLATION AND COMMISSIONING

"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.
				5	1
				9	6
Pin N°		Signal name	Polarity			Comments
1		GND		Ground (no connected)
	6	RXPB	(+)	Input for data received over the P interface and sampled on the
				rising edge of receive clock RXCLKP (B-A)
2		RXPA	(-)
	7	TXPB	(+)	Output for data sent over the P interface on the falling edge of
				transmit clock TXCLKP (B-A)
3		TXPA	(-)
	8	TXCLKPB	(+)	Output for transmit clock; in codirectional mode, the transmit clock
				timing is derived from the equipment's internal timing
4		TXCLKPA	(-)
	9	RXCLKPB	(+)	Receive clock input
5		RXCLKPA	(-)

*In slave contradirectional mode (coming) TXCLK signals are inputs.
