This equipment is not designed for making emergency telephony calls when the power fails. Alternative arrangements should be made for access to emergency services. Access to emergency services can be affected by any call-barring function of this equipment.
A Cisco one-port ISDN-BRI WAN interface card with an S/T interface can be installed in any interface card slot in a Cisco 2600 series, Cisco 3600 series, or Cisco 3700 series router, where it provides one ISDN-BRI connection at the S-reference point. A WIC of this type supports S-bus sharing, and does not require a dedicated S-bus connection for each ISDN port. The ISDN usage is restricted to point-to-point mode only.
To ensure that common network timing exists between the ISDN ports, the ISDN network connection must be provided by a single network vendor or public telecom operator (PTO). Connection to multiple vendors or operators may result in lost (nonrecoverable) data packets because of timing slips.
A WIC of this type can be installed in any compatible host chassis with no impact on the capabilities, functionality, or performance of the BRI WAN interface card.
The following agency compliance apply to Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series routers:
UL 60950 3rd Edition; CAN/CSA C22.2 No. 60950-00 3rd Edition; IEC 60950:1999, EN 60950:2000; AS/NZS 3260: 1993 with Amendments 1, 2, 3, and 4; TS001: 1996 with Amendment 1
