DBM Configuration Options

Single Rate: Yes

Next Yes No Prev

Single Rate (only displayed when Full Mode is enabled). Determines whether the DBM will adjust its rate to resolve a rate mismatch with a remote DBM or modem with the following limitations.

NOTE: If the DBM Rate(Kbps) is set to 2.4, the DBM will only train at 2.4 kbps and can only talk to a 2.4 kbps modem,

 

regardless of how Single Rate is set.

Yes

Ð

Select when you want the DBM to only operate at the rate for which it is configured.

No

Ð

Select when you want the DBM to adjust its rate downward to correct a rate mismatch.

AutoAnswer: Enab

Next Enab Disab Prev

Automatic Answer (only displayed when Full Mode is enabled). Controls whether the DBM answers incoming calls.

Enab

Ð

Select if the DBM is to automatically answer incoming calls.

Disab

Ð

Select if the DBM is not to automatically answer incoming calls.

TxElasStor: Disab

Next Enab Disab Prev

Transmit Elastic Store (only displayed when Full Mode is enabled and a TDM/Flex is not installed). Using a transmit buffer on the DBM's transmitted data (TXD) lead, serial data is clocked into the DBM's elastic store using clock provided by the extended circuit received clock lead. The DBM's own system timing is used to clock data out of the buffer.

Transmit Elastic Store is reset each time the unit powers-up, the buffer overflows, or after the RTS lead makes an Off-to-ON transition.

Enab

Ð

Select enable when interfacing with a DCE that receives clock from its own network source (e.g., a T1

 

 

MUX or DSU that is on the DDS network).

Disab

Ð

Select disable if you do not have an extended network or are providing the clock source to the extended

 

 

network (e.g., LADS with external clock).

RxElasStor: Disab

Next Enab Disab Prev

Receive Elastic Store (only displayed when Full Mode is enabled). The DBM receives data using a receive data buffer on the DBM's received data (RXD) lead. This configuration option only supports single-port DBMs configured for disruptive diagnostics (Diag Type is set to Disr) and no rate adaption ± when Rate(Kbps) is equal to PrtSp(Kbps). Both the control and tributary DBMs must be configured the same.

Enab

Ð

Select enable when interfacing with a DCE that receives clock from its own network source and does not

 

 

support a Transmit Elastic Store.

Disab

Ð

Select disable if you do not have an extended network.
