Overview of the Cisco 2524 and Cisco 2525 Routers
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:
The choice of ISDN WAN modules is as follows:
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.
The Cisco 2524 and Cisco 2525 routers include the following features:

The following text is required for FCC Part 68 regulatory compliance:
The equipment complies with Part 68 of the FCC rules. On the bottom of the equipment is a label that shows the FCC registration number.
If the equipment causes harm to the telephone network, the telephone company may temporarily discontinue service. If possible, advance notification is given; otherwise, notification is given as soon as possible. The telephone company will advise the customer of the right to file a complaint with the FCC.
The telephone company may make changes in its facility, equipment, operations, or procedures that could affect the proper operation of the equipment; advance notification and the opportunity to maintain uninterrupted service will be given.
If you experience difficulty with the Cisco 2524 or Cisco 2525 router, please contact Cisco Systems at 800 553-NETS (6387) or 408 526-4000 for repair and warranty information. If your equipment is causing harm to the telephone network, the telephone company may request that you disconnect the equipment until the problem is resolved.
The module contains no user-serviceable parts.
An FCC-compliant telephone cord and a modular plug is provided with the equipment. The equipment is designed to be connected to the telephone network or premises wiring using an FCC-compatible modular jack that is Part 68 compliant.
Table 1-2 lists information that may be required when applying to the local telephone company for leased-line facilities.
