Nortel VPN Router Installation — VPN Router 2700

ISDN BRI interface card

The ISDN BRI S/T and ISDN BRI U interface cards have a single RJ-45

connector that provides the signals needed to interface to ISDN equipment. (To

connect the ISDN S/T interface to the ISDN network, you must attach an external

NT-1 device to the RJ-45 connector.)

Figure 38 shows the ISDN BRI S/T interface card or the ISDN BRI U interface

card. Both interface cards look the same.

Figure 38 ISDN BRI S/T interface card or ISDN BRI U interface card

The connector on the ISDN BRI S/T and ISDN BRI U interface cards

accommodates an 8-pin RJ-45 modular patch cord. These cables are sold as

Category 5, or Ethernet, cables.

Table 27 provides the ISDN BRI S/T cable pinouts.

Note: Nortel does not supply a cable with the ISDN BRI interface cards.
