5.5 Connecting ISDN E1/T1 Interfaces
This section describes how to cable the PRI interfaces.
5.5.1 Connecting to ISDN PRI (E1/T1) Trunks
The procedure below describes the cabling of the device's E1/T1 (PRI) trunk interfaces.
Warning:
• PRI port cabling must be routed only indoors and must not exit the building.
• To protect against electrical shock and fire, use a 26 AWG min wire to connect T1
or E1 ports to the PSTN.
• To comply with EMC rules and regulations, use shielded twisted pair (STP) cables
for E1 interfaces.
Note: PRI interfaces are a separate orderable item.
Cable specifications:
 Cable: STP cable of 26 AWG min.
 Connector Type: RJ-48c
 Connector Pinouts:
