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.

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
