Sagem ADR 155C Connecting on the ADR IC1.x card, Connecting STM1 interface, TR and REC ports

1 - INSTALLATION AND COMMISSIONING

1.3.3 - Connecting on the ADR IC1.x card

Each ADR IC1.x module provides connection for:

San STM1 interface ("TR" transmission port and "REC" reception port)

two order wire channels at 64 kbit/s (named "EOW" and "AUX"), which, by default, are conveyed in E1 and F1 bytes of the SOH, respectively.

1.3.3.1 - Connecting STM1 interface

Remove the contact protection connector,

Connect STM-1 interface to front panel FC/PC connectors:

÷Transmission	TR Connector
Reception	REC Connector
"TR" and "REC" ports:
Interface Type	IC 1.1 = L 1.1 + S 1.1 or IC 1.2 = L 1.2 + S 1.2,
Bit rate	155.520 Mbit/s ± 15 ppm,
Standart	ITU-T G.957/G.958,
Encoding	Not encoded (NRZ),
Optical fiber*	Single mode (1300 nm (IC1.1) or
	1550 nm (IC1.2), ITU-T G.652),
Transmit optical power	-5 to 0 dBm
Max. receive power	0 dBm
Sensibility at 10-10	- 34 dB
garanteed Attenuation	0 - 28 dB with no external attenuator,
Typical range	0 - 60 km (IC1.1) or 0 - 90 km (IC1.2),
Connector	all ceramic FC/PC

*: It is possible to use a multi-mode optical fiber with diameter smaller than or equal to 62.5 microns. The optical budget is then reduced to 25 % of the optical budget obtained with a mono-mode optical fiber. The transmission optical fiber is mono-mode type and the reception optical fiber is multi-mode type.

1.3.3.2 - Connecting order-wire channels

"EOW" and "AUX" Interface:

Port	synchronous V.11 (differential),
Bit rate	64 kbit/s,
