Figure 2. Express 6530 Functional Overview

The Express 6530 can be powered from any AC power source ranging from 90 V to 240 V at frequencies of 50 Hz to 60 Hz, or a nominal -48 VDC power source.

The SHDSL NTU will be used to provide access to customer premises to E1 or Nx64k leased-line services, as well as primary-rate ISDN. The SHDSL NTU is required to support leased-line G.703/G.704 and/or Nx64k services to customers. The primary applications will include connection to routers and PABXs.

Front Panel Features

The Express 6530 unit has eight front panel LEDs. Table 1 lists and describes these front panel LEDs.
