ABSTRACT:
A method and apparatus for increasing the capacity of a remote terminal cabinet and providing ISDN Basic Rate Interfaces to the remote cabinet which otherwise has insufficient additional physical slots to support such ISDN Basic Rate Interfaces is described. The method features removing any protective covering from a space previously designated for but lacking a protection block equipment and installing in the space ISDN Basic Rate Interface equipment. The installation includes securing the equipment physically in place and connecting the equipment for communications with a T1 carrier service at a first interface and a plurality of ISDN BRI interfaces to customer premises lines at a second interface. The remainder of the remote cabinet communications is left unaffected.
