FiberReach shelves. Application for business customers, the private network, cell
sites, PBXs, customer premises equipment (CPE), and other applications are
supported.
The BBF8 circuit pack fits into the low-speed slots and provides two, four-wire
HDSL interfaces. Each interface provides a full DS1 rate payload capacity
mapped to a SONET VT1.5 and then VT cross-connected into an STS-1. Once in
SONET, DS1 rate payload is treated as a normal DS1.
