Outside North America, ISDN S/T interface models:
These models were designed for international (outside North America)
markets where the NT1 is typically provided by the ISDN service
provider. These models have one
ISDN S/T jack on the rear of the router
where the ISDN line is plugged in.
Note: Refer to Chapter 1 for more details on ordering and configuring an
ISDN line.
International (outside North America) Configuration: S/T Interface
Instructions
1. Plug one end of the ISDN cable (blue label marked “ ISDN or
ADSL ”) into the RJ45 jack marked ISDN S/T on the back panel of
the router.
2. Plug the other end of the cable into the S/T bus RJ45 ISDN wall
jack.
Note 1: You may connect multiple devices on the same wire in a
multi-point bus configuration with a splitter. If the router is in a
multi-point bus configuration and it is not on either end of the bus,
switches controlling termination must be set to off (See Appendix
A).
Note 2: Routers outside North America do not have an ISDN U
interface connector.
