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:
The console cable is an RJ-45, the CAB-1600-CON=.
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.
1Pins 3, 4, 5, and 6 are not used.
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
The table below shows the front panel LED functions for the Cisco 1601 and 1602 routers.
|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||
|SER 0 ACT||Green||
The table below explains the rear panel LEDs and their functions.
|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.|
|RDY||Green||A serial port cable connection has been made to a modem or DSU/CSU.|
|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.|
|OK (next to ISDN BRI0 S/T port)||Green||A physical connection has been established with the ISDN central office switch.|
|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.|
|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.|
