DB-9 Connector Pinouts for the Routing Engine AUX/MODEM and CONSOLE Ports

The ports on the Routing Engine labeled AUX/MODEM and CONSOLE are DB-9 receptacles that accept RS-232 (EIA-232) cable. The AUX/MODEM port connects the Routing Engine to a laptop, modem, or other auxiliary unit, and the CONSOLE port connects it to a management console. The ports are configured as data terminal equipment (DTE). For more information, see “Routing Engine Interface

Ports” on page 16. Table 26 on page 200 describes the DB-9 connector pinouts.

RJ-48 Cable Pinouts for E1 and T1 PICs

The E1 and T1 PICs use an RJ-48 cable, which is not supplied with the PIC.

CAUTION: To maintain agency approvals, use only a properly constructed, shielded cable.

Table 27 on page 200, Table 28 on page 201, Table 29 on page 202, and Table 30 on page 203 describe the RJ-48 connector pinouts.
