2.2.1 Mounting the Stand Alone Modem
The stand alone modem comes with mounting screw holes to facilitate wall mounting, rack
mounting, or dual (side-by-side) rack mounting. There are seven screw holes on each side of the
modem; however, it is not necessary to use each hole for all configurations. The diagram below
indicates the holes required for each configuration.

2.2.2 Cabling the Stand Alone Modem
Make sure all cables are clearly labeled and set away from foot traffic. Attach the appropriate
cables to the modem's ELIMs and OLIMs. Optical fiber cables should be marked to distinguish
them from cables containing other services. If no Configuration (CFG Alarm LED) errors are
detected, data will begin passing.
The EdgeAccess Model 2461 E1 Modem is code transparent, it does not generate HDB3 coding.
Therefore, it is not to be used for direct connection to the PSTN. However, it can be connected to
the PSTN provided the compatible approved terminal equipment shall either supply signals with
HDB3 encoding or be approved for connection directly to the PSTN.
2.3 Stand Alone Modem Alarm Relay Contacts
