1.3.3 - Connecting on the ADR IC1.x card
Each ADR IC1.x module provides connection for:
an 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,

* : 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.
