3.3.3.1 Connecting E1/T1 PSTN Interfaces
Note:
Cabling of the E1/T1 interfaces is applicable only when implementing the
Mediant 3000 with the 8410 blade.
The RTM-8410 provides a SCSI connector(s) for interfacing with the E1/T1 trunks. The
number of SCSI connectors depends on the supported E1/T1 spans:
42-84 spans configuration:
Two SCSI connectors:
•
100-Pin female SCSI connector.
•
68-Pin female SCSI connector.
16-spans configuration:
A single 100-pin female SCSI connector.
