CRAFT INTERFACE

Connection to the Total Access 1248 system can be made

through the DB-9 connector, labeled

CRAFT, located on the

front of the 1248/1200F Host unit. A DB-9 straight cable is

required.

Most personal computers or laptops can run communications

software that will emulate a VT100 terminal. Windows

programs such as Terminal or HyperTerminal are two such

examples in the Windows format, but there are many other

adequate, commercially available software packages, virtually

all of which allow the PC or laptop to emulate a VT100

terminal. Certain configuration items must be set on a PC or

laptop to act as a VT100 terminal for the Total Access 1248.

1. Set the parameters of the communications software to

the following settings:

♦ 9600 baud rate

♦ 8 data bits

♦ No parity

♦ 1 stop bit

♦ No flow control

2. Set the PC for direct connect on the appropriate

communications port (as opposed to dial up

connection).

3. Plug the male end of the data cable into the Total

Access 1248. Make connection to the PC or laptop as

appropriate for the equipment.

TOTAL ACCESS 1200F CONVERSION

The order of subtended Total Access 1200 Series DSLAMS

must be preserved when connecting to the Total Access

1200F for translation to the legacy ATM mode PVCs. See

the following table.

Existing Total Access 1200 Series DSLAM installations require

a software upgrade to convert the Total Access 1200 Series

DSLAMs to function with a Total Access 1200F.

To upgrade each Total Access 1200 Series DSLAM, perform

the following steps:

Total Access 1200F

Expansion Port

Total Access 1200 Series Client

Total Access 1200 Series Host

Craft Port

Upgrading the firmware disrupts DSL service to the

customer.

1. Connect a VT100-capable laptop/terminal to the

CRAFT

port of a Total Access 1200 Series DSLAM.

2. Set the terminal baud rate to 9600 baud, 8 data bits,

no parity, 1 stop bit, and no flow control.

NOTE

The 4-MB Flash Upgrade must be made at 9600 baud.

3. Press and hold the

Y key on the terminal keyboard and

apply power to the Total Access 1200 Series DSLAM.

When prompted, select 38400 for a faster transfer rate

(20 minutes at 38400 compared to 60 minutes at

9600).

4. If using HyperTerminal, go off-line, select properties,

change the baud rate, then go back online. VT100

settings should be set as follows:

♦ Baud Rate: 38400

♦ Data Bits: 8

♦ Parity: None

♦ Stop Bits: 1

♦ Flow Control: None

If properly connected, a row of CCCCs should begin to

display on the screen.

5. Download the current file identified by network

administration using the Y-Modem protocol.

If using HyperTerminal, use the Transfer > Send File...

Browse... dialogue box and identify the file by name

and location. Select YModem, then click Send.

6. Several messages are displayed that report system

progress for the upgrade procedure, including the

following:

♦ Erasing Flash

♦ Erase Complete

♦ Programming Flash

♦ Programming Complete

♦ Comparing Flash to SDRAM

♦ Verify Done

♦ Please set Baud Rate to 9600 and Reboot Unit Now

7. Reboot the Total Access 1200 Series DSLAM when the

download is completed.

8. Repeat steps 1 through 7 for each Total Access 1200

Series DSLAM.

9. Connect the Total Access 1200F expansion cables at

the DSLAM end.

10. Provision, test, and turn up the equipment. Refer to

“Section 4, Provisioning Defaults” and “Section 5, User

Interface” of the Total Access 1200F Installation and

Maintenance Practice (P/N 61179660L1-5) for detailed

instructions on provisioning the equipment.
