Return to On-line Data State

The Return to On-line Data State Command

O

instructs the CTA 500dm to return to the On-line Data State.

Use this command to determine the number of B-channels active for rate adaptation protocols that use more than one B-channel, since the aggregate network rate is returned by the CONNECT indication.

Result Codes

CONNECT rate Appears when the connection is successfully resumed, where rate is the aggregate network rate (56000, 64000, 112000, or 128000).

Immediately after this connection rate is sent, the CTA 500dm enters the data mode.

The 112000 and 128000 rates are sent only if both channels on the TCM link are in use.

NO CARRIER Appears when the connection could not be reestablished.

Enter Download State

The Enter Download State Command

Y[password]

instructs the CTA 500dm to enter the download state and prepare for the transfer of a Þle that updates the Flash EPROM. Sets the baud rate at 9600 bit/s. The password is always Nor*.

After the Þle transfer has begun, disconnecting the CTA 500dm from the attached PC or from the power supply, will put it into the Download State when it is powered back up. This is caused by loss of the Flash EPROM contents.

Immediately after the command is executed, the CTA 500dm sends a single line indication SEND PROGRAM FILE USING YMODEM-G (periodically sending GÕs until the download is started). The CTA 500dm then enters the download mode.

After Flash programming is complete, a single line indication of OK is sent.
