Figure 1. Express 6530 SHDSL NxNTU

Line (SHDSL) technology to transport data over a single copper loop. The Express 6530 interfaces between the incoming ITU G.991.2 (SHDSL) leased-lineservice and the customer’s Data Terminal Equipment (DTE), providing solutions forLAN-to-LANbridging, 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 215-1pseudorandom 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.

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 -48VDC power source.

The SHDSL NTU will be used to provide access to customer premises to E1 or Nx64K leased-lineservices, as well asprimary-rateISDN. The SHDSL NTU is required to supportleased-lineG.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 indicates 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.

REMOTE LOOP

 

If the SHDSL port is selected, then pressing the button will

 

 

initiate/terminate a remote loopback test on the port by

 

 

sending a request message to the remote unit. If the

 

 

Nx64K port or G.703 port (with only one service defined)

 

 

is selected, then pressing the button will initiate/terminate a

 

 

remote loopback test on the selected port's single data

 

 

service by sending in-bandloop up/down patterns to the far

 

 

end.

 

 

 

 

 

If a port is selected and there are no local loopback tests

Cross-ConnectMap

The purpose of the cross-connectmap is to allocate the time slots (TS0s) from the SHDSL loop to user ports (E1, V.35/X.21) and configure framing. Thecross-connectmaps can be accessed via the VT100 terminal screens. Select “1,”Provisioning, from the Main Menu. Choose to provision the local unit (Selection 1) or the remote unit (Selection 2). Next, select “1,”Unit Options, and then “3,”Cross Connect Map. Thecross-connectmap is shown inFigure 6.

The cross-connectmap is split down the middle in two sections. The left section of the map lists the SHDSL time slots and right section of the map lists the G.703 time slots. The user builds a new pending map before making it active with the apply key. The options listed at the bottom of the screen allow the user to setup and manipulate the time slots. The statement under the list of commands indicates the framing status. Time slot configuration options are defined as follows:

0. Idle

If a time slot is set for idle, an idle code is inserted. The pattern will always be FF hex (all 1s) toward the SHDSL network.

The idle pattern out the G.703 interface is programmable under the G.703 option. The default is value FF hex (all 1’s).

1. - 31. G.703 Service

The selected time slot will carry G.703 service (Refer to the Full G.703 Services subsection for more information).

32. G.704 Framing

This option enables three different framing configurations. Framing is always set in the first time slot (TS0). The framing will be locally generated if 32 is entered in the G.703 TS0 slot only. If 32 is entered in the G.703 TS0 and the SHDSL TS0, then the framing will be passed transparently between the G.703 and SHDSL ports. If values other than 32 are assigned to both the SHDSL TS0 slot and G.703 TS0 slot then the operation is G.703 unframed (if other G.703 service values are assigned to the G.703 time slots).

33. Nx64K Service

The selected time slot will carry Nx64K service. The value assignment is only valid for the SHDSL time slots.

A. Apply New Map

This command saves and activates any changes made by the user.

U. Undo New Map

This command will undo any changes made by the user since the last saved configuration. The new pending map will revert to the currently active time slot assignments.

G. Full G.703 Service

If this quick key command is selected, the crossconnect map will automatically configure the time slots for Full G.703 service, and the framing will be set for transparent. Refer to the Typical Applications subsection for more information.

N. Full Nx64K Service

If this quick key command is selected, the cross-connectmap will automatically configure the time slots for full Nx64K service. Refer to theTypical Applications subsection for more information.

Tab. Select SHDSL or G.703 Timeslots

The tab key moves the cursor between the SHDSL and G.703 sections of the cross-connectmap.

Arrow Keys. Move Cursor

The arrow keys allow movement between the individual time slots.

G.703 Service Time Slots

A service is comprised of an arbitrary collection of time slots from the SHDSL interface that shall be configured via the management interface. Time slot allocation on an ordered noncontiguous basis is possible with each time slot within a service having the same delay. An example is illustrated in Figure 7.

All unused time slots contain a configurable bit pattern that is set via the management interface. The default bit pattern is all 1s. Unused time slots are those which are sent out of the G.703 port, but are not part of a service. The G.703 port transmits the unused time slot patterns, and the receive ignores the unused time slots.

The service values (1-31)correlate to the G.703 Services test options. These options provide the capability to loopback and test time slots by service value, so as not to affect other services in surrounding time slots.
