Introduction

This document provides the cabling specifications for the Cisco 1604-R Ethernet/ISDN-BRI Modular router.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on the hardware version:

  • Cisco 1604-R Router

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

For more information on document conventions, see the Cisco Technical Tips Conventions.

Cabling Specifications

The Cisco 1604-R router has one Ethernet interface, one Integrated Services Digital Network (ISDN) interface, one ISDN phone port, and one ISDN-Basic Rate Interface (BRI) WAN interface card (WIC) slot.

The cabling details for the Cisco 1604-R are as follows:

Console

The console cable is an RJ-45, the CAB-1600-CON=.

Ethernet

On the 1604-R router, there is one functional port for either the 10Base-T (RJ-45) or AUI (DB-15). The cable details are:

  • CAB-ETH-S-RJ45=

  • Yellow Cable for Ethernet

  • Straight-through

  • RJ-45

  • 6 ft.

The AUI adapter cable is a CAB-3CE18=.

ISDN BRI U Interface

On the 1604-R router, there is one ISDN BRI U interface with integrated NT-1 which requires an RJ-45 straight-through cable.

The cable details are:

  • CAB-U-RJ45=

  • Red Color Cable for ISDN BRI U

  • RJ-45

  • 6 ft.

The table below shows the ISDN BRI U port pinouts for the RJ-45.

8-Pin1 Function
3 No connection
4 Signal --- Tip or Ring
5 Signal --- Tip or Ring
6 No connection

1Pins 1, 2, 7, and 8 are not used.

The table below shows the BRI Cable (RJ-45 to RJ-45) pintouts.

NT7 RJ-45 (8 Pin)8 Wire LT1 RJ-45 (8 Pin)
4 Tip 4
5 Ring 5

1 LT refers to the line termination point (that is, at the wall jack).

ISDN BRI Cable Specifications

The table below provides the cable specifications of the ISDN BRI cable.

Specification High-capacity Cable Low-capacity Cable
Resistance (at 96 kHz) 160 ohms/km 160 ohms/km
Capacity (at 1 kHz) 120 nF1/km 30 nF/km
Impedance (96 kHz) 75 ohms 150 ohms
Wire diameter 0.024" (0.6 mm) 0.024" (0.6 mm)
Distance limitation 32.8' (10 m) 32.8' (10 m)

1 nF = nanoFarad.

ISDN S/T Interface for a downstream ISDN phone or fax

The ISDN S/T interface requires an RJ-45 straight-through cable.

Note: You cannot connect the 1604-R to the ISDN network through the S/T port.

The table below provides the ISDN BRI S/T port pinouts for the RJ-45.

8 Pin1 TE2 NT3 Polarity
3 Transmit Receive +
4 Receive Transmit +
5 Receive Transmit -
6 Transmit Receive -

1Pins 1, 2, 7, and 8 are not used.

2TE refers to terminal equipment Layer 1 aspects of TE1, TA, and NT functional groups. This applies to the Cisco 1603 and the ISDN BRI S/T WAN interface card.

3NT refers to network terminating Layer 1 aspects of NT1 and NT2 functional groups. This applies to the Cisco 1604 ISDN S/T port.

WAN Interface Cards

WAN interface cards supported on the Cisco 1604-R consist of the following:

  • WIC-1T: 1-port serial, async and sync (T1/E1)

  • WIC-1DSU-56K4: 1 serial with integrated 56/64 Kbps 4-wire DSU/CSU

  • WIC-1DSU-T1: 1 serial with integrated T1/Fractional T1 DSU/CSU

Front Panel LEDs

The table below shows the front panel LED functions for the Cisco 1603 and Cisco 1604 routers.

LED Color Description
SYSTEM PWR Green The router is on, and DC power is being supplied.
SYSTEM OK Green The router has successfully booted. Blinks during the boot cycle.
LAN ACT Green Data is being sent to or received from the local Ethernet LAN.
LAN COL Yellow Flashing indicates packet collisions on the local Ethernet LAN.
BRI 0 B1 Green
  • An ISDN connection on B-channel 1.
  • Cisco 1604 only --- If an ISDN device connected to the ISDN S/T port is using B-channel 1, the LED turns on.
BRI 0 B2 Green
  • An ISDN connection on B-channel 2.
  • Cisco 1604 only --- If an ISDN device connected to the ISDN S/T port is using B-channel 2, the LED turns on.
WIC CD Green Active connection on the WAN interface card serial port.
WIC ACT Green Data is being sent over the WAN interface card serial port.

Rear Panel LEDs

The table below explains the rear panel LED functions.

LED Color Description
All Models
LNK (next to ETHERNET 10BASET) Green Indicates 10BaseT link integrity. This LED is not on when connected to an Ethernet network through the AUI port. The Cisco 1605 has two LNK LEDs, one for each Ethernet 10BaseT port.
OK (next to FLASH PC CARD slot) Green The Flash PC card is correctly installed.
Cisco 1601
RDY Green A serial port cable connection has been made to a modem or DSU/CSU.
Cisco 1602
LOOPBACK Yellow The DSU/CSU is in DSU or CSU loopback mode.
ALARM Yellow An alarm condition exists on the DSU/CSU port.
CARRIER Green Indicates line synchronization or connection on the DSU/CSU port.
Cisco 1603
OK (next to ISDN BRI S/T port) Green A physical connection has been established with the ISDN central office switch.
Cisco 1604
NT1 Green A physical connection has been established from the router internal NT1 to the ISDN central office switch.
OK (next to ISDN PHONE port) Green The device connected to the router ISDN S/T port has established a physical connection with the ISDN central office switch.
Cisco 1605
LNK (next to ETHERNET1 10BASET) Green Indicates 10BaseT link integrity for the Ethernet 1 port.
OK (next to WIC slot) Green The WAN interface card is correctly installed in the router.
