1. GENERAL

This practice contains installation and maintenance information for the Express 6530 SHDSL NxNTU, P/N 1225101L1. The unit is illustrated in Figure 1. The ADTRAN Express 6530 is a network terminating unit using Single-Pair High Speed Digital Subscriber

61225101L1-5B 1

Line (SHDSL) technology to transport data over a single copper loop. The Express 6530 interfaces between the incoming ITU G.991.2 (SHDSL) leased-line service and the customer’s Data Terminal Equipment (DTE), providing solutions for LAN-to-LAN bridging, Frame Relay, and/or PBX termination.

The Express 6530 is a locally powered standalone unit which contains an integrated Data Service Unit (DSU), eliminating the need for a separate DSU. The Express 6530 interfaces to a customer’s G.703, V.35, or X.21 interfaces and can be provisioned to support simultaneous G.703 and Nx64 services. The SHDSL interface is designed to operate from 192 kbps to

2.304 Mbps in 64 kbps increments or from 3 to 36 time slots, with each time slot representing 64 kbps. The SHDSL time slots can be multiplexed to the G.703 and/or the Nx64 interfaces. The maximum number of time slots that can be directed toward the G.703 interface is 32 (2.048 Mbps), while the Nx64 can support 36 (2.304 Mbps). A block diagram of the Express 6530 functionality is illustrated in Figure 2.

The Express 6530 can be deployed in pairs for a local campus application or to an LTU located in a Central Office. The Express 6530 can be locally or remotely provisioned with local provisioning being accomplished through the V.28 control port using a dumb terminal or PC with a terminal emulation program. The Express 6530 can be remotely provisioned by another Express 6530 or an ADTRAN SHDSL LTU. The Express 6530 can initiate and respond to local and remote loopbacks and has an

internal 2

-1 pseudorandom test pattern for bit error testing. Front panel-mounted LEDs and pushbuttons provide interface and test status as well as the initiation of a remote or local loopback.

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.

The Express 6530 has four front panel pushbuttons. The buttons are protected from accidental operation. The front panel button functions can be disabled via the management interface. It is possible to disable the port select SHDSL option to avoid the possibility of looping the SHDSL port when disabled. Table 2 lists and describes these four pushbuttons.

The “Port Select” button operates in the following manner:

1. When no port has been selected (indicated by none of the port LEDs flashing), then only the “Port Select” button is enabled and the LL, RL and BERT LEDs are an ordered summation of the test states of the Nx64k, G.703 and SHDSL interfaces.

2. The Port Select button cycles through the following ports on each successive press:

• Nx64k

• G.703

• SHDSL (only if enabled via the EOC)

• No Selection

3. When the Nx64k port is selected, the Nx64k LED will flash as an indication. The Local Loop/Err Inj, Remote Loop and BERT buttons will initiate/ terminate tests and the corresponding LEDs indicate the status of tests on this port only.

4. When the G.703 port is selected, the G.703 port LED flashes as an indication.

If there is only a single service on the G.703 port then the Local Loop/Err Inj, Remote Loop and BERT buttons initiate/terminate tests and the corresponding LEDs indicate the status of tests on this port only.

If there are multiple services, the G.703 port Local Loop/Err Inj, Remote Loop, and BERT buttons are disabled, and the corresponding LEDs indicate the status of tests on this port only (initiated from sources other than the front panel buttons).

5. When the SHDSL port is selected, the SHDSL port LED flashes as an indication. Note that the SHDSL port select can only occur if enabled via the management interface. The Local Loop/Err Inj, Remote Loop, and BERT buttons will initiate/terminate tests and the corresponding LEDs indicate the status of tests on this port only. These tests are on the aggregate SHDSL payload

Port Select will not operate if any locally initiated tests are in progress.
