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
