Overview of the Cisco 2524
and Cisco 2525 Routers
1
The Cisco 2524 and Cisco 2525 routers provide LAN and WAN access in a low-cost
modular router platform that can grow with your internetworking needs. The Cisco 2524
offers an Ethernet (attachment unit interface [AUI] or 10BaseT) LAN connection, and the
Cisco 2525 offers a Token Ring (shielded twisted-pair [STP] or unshielded twisted-pair
[UTP]) LAN connection. Both routers can accommodate up to three WAN modules—two
synchronous serial and one Integrated Services Digital Network (ISDN).
The choice of synchronous serial WAN modules is as follows:
•2-wire switched 56-kbps data service unit/channel service unit (DSU/CSU)
•4-wire 56/64-kbps DSU/CSU
•Fractional T1/T1 DSU/CSU
•Five-in-one synchronous serial
Note The five-in-one synchronous serial WAN module gets its name from the five types
of signaling it supports: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can
order from Cisco Systems a DB-60 shielded serial transition cable. The router end of the
shielded serial transition cable has a DB-60 connector; the other end of the cable has the
appropriate connector for the standard interface you specify.
The choice of ISDN WAN modules is as follows:
•ISDN Basic Rate Interface (BRI)
•ISDN with integrated network termination 1 (NT1) device

Features
The ISDN WAN modules are designed so that you cannot insert them into the synchronous
serial WAN slots. A blank slot cover is installed over unused slots.
Features The Cisco 2524 and Cisco 2525 routers include the following features:
•Three slots for WAN modules
•One Ethernet (AUI or 10BaseT) interface on the Cisco 2524 router
•One Token Ring (STP or UTP) interface on the Cisco 2525 router
•Dynamic random-access memory (DRAM) for main system memory and shared
memory
•Nonvolatile random-access memory (NVRAM) for storing configuration information
•Flash memory for running Cisco IOS software
•EIA/TIA-232 console port for connecting a console terminal
•EIA/TIA-232 auxiliary port for connecting a terminal or modem
Note EIA/TIA-232 and EIA/TIA-449 were known as recommended standards RS-232
and RS-449 before their acceptance as standards by the Electronic Industries Association
(EIA) and Telecommunications Industry Association (TIA).
