Cable Specifications

The 1602-R Ethernet/Serial Modular Router has one Ethernet interface, one Serial interface with 56 K Data Service Unit (DSU) (4-wire), and one WAN interface card (WIC) slot.

The cabling specifications for the Cisco 1602-R are as follows:

Console

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

Ethernet Interface

On the 1602-R router, there is one functional port for either the 10Base-T (RJ-45)or the AUI (DB-15). The cable details are: CAB-ETH-S-RJ45= Yellow cable for Ethernet, Straight-through, RJ-45, 6 ft.

Serial Interface

The Serial interface is a 56 K, 4-wire data service unit/channel service unit (DSU/CSU) for an RJ-45 cable. The telco RJ45 designation is the same as the RJ-48S.

The cable details are: CAB-DSU-RJ45= Blue Color Cable for DSU/CSU, RJ-45, 6 ft.

The table below lists the pin layout of the 56-kbps DSU/CSU (RJ-45) cable and its descriptions.

8 Pin¹	Description
1	Transmit
2	Transmit
7	Receive
8	Receive

¹Pins 3, 4, 5, and 6 are not used.

WAN Interface Cards (WICs)

WAN interface cards supported on the Cisco 1602-R consist of the following:

WIC-1T: 1-port serial, aynchronous and synchronous (T1/E1)
WIC-1DSU-56K4: One serial with integrated 56/64 Kbps 4-wire DSU/CSU
WIC-1DSU-T1: One serial with integrated T1/Fractional T1 DSU/CSU
WIC-1B-S/T: One ISDN BRI S/T
WIC-1B-U: One ISDN BRI U with integrated NT-1

Front Panel LEDs

The table below shows the front panel LED functions for the Cisco 1601 and 1602 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.
SER 0 CD	Green	Cisco 1601 has an active connection on the serial port. Cisco 1602 has an active connection on the DSU/CSU port.
SER 0 ACT	Green	Cisco 1601 serial port is sending or receiving data. Cisco 1602 DSU/CSU port is sending or receiving data.
WIC CD/B1	Green	Serial WAN interface card has an active connection on the serial port. ISDN WAN interface card has an ISDN connection on B-channel 1.
WIC ACT/B2	Green	WAN interface card serial port is sending or receiving data. WAN interface card ISDN port has a connection on B-channel 2.

Rear Panel LEDs

The table below explains the rear panel LEDs and their functions.

LED	Color	Description
All Models
LNK (next to Ethernet0 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 BRI0 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.
