System Specifications 3-15

External Connections

• 1-port dual attachment single-mode FDDI

The XMTR and RCVR ports use simplex, FC-type connectors.

• 2- or 4-port synchronous serial

Serial interfaces supported by these modules: EIA-530, EIA/TIA-232, EIA/TIA-449, V.35, and

X.21. All can be conﬁgured as nonreturn to zero inverted (NRZI), nonreturn to zero (NRZ), and

DCE or DTE (except EIA-530, which is DTE only). Serial cables have DB-50 connectors for the

two port module, and DB-60 connectors for the four port module.

• 4- or 8-port ISDN BRI

Uses RJ-45 8-pin connectors.

• 1-port channelized T1/ISDN PRI

Uses a 15-pin, DB-15 connector.

• 1-port channelized E1/ISDN PRI (balanced or unbalanced)

Uses a 15-pin, DB-15 connector.

• 4-port serial G.703 (balanced or unbalanced)

Uses 15-pin, DB-15 connectors.

• 1-port ATM (single-mode or multimode) OC-3c

Uses a duplex SC connector.

• 1-port ATM DS-3

Uses a duplex SC connector.

• 1-port ATM E3

Other External Connections

This section includes the other external connection requirements for Cisco 4000 series systems.

• The data communications equipment (DCE) console port uses a male DB-25 connection, and the

data terminal equipment (DTE) auxiliary port uses a female DB-25 connection. (A standard

EIA/TIA-232 cable can be used for either.)

• The Cisco 4000 series chassis can be optionally rack- (standard 19 inch and Telco), slide-, desk-

(top or side), or wall-mounted.
