Configuring the Unit5-133550-A2-GB20-40 July 1999Table 5-6(2 of 4)DBM Configuration OptionsSingle Rate: YesNext Yes No PrevSingle Rate (only displayed when Full Mode is enabled). Determines whether the DBM will adjust its rate to resolve arate 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 — Select when you want the DBM to only operate at the rate for which it is configured.No — Select when you want the DBM to adjust its rate downward to correct a rate mismatch.AutoAnswer: EnabNext Enab Disab PrevAutomatic Answer (only displayed when Full Mode is enabled). Controls whether the DBM answers incoming calls.Enab — Select if the DBM is to automatically answer incoming calls.Disab — Select if the DBM isnot to automatically answer incoming calls.TxElasStor: DisabNext Enab Disab PrevTransmit Elastic Store (only displayed when Full Mode is enabled and a TDM/Flex is not installed). Using a transmitbuffer on the DBM’s transmitted data (TXD) lead, serial data is clocked into the DBM’s elastic store using clock providedby 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 anOff-to-ON transition.Enab — Select enable when interfacing with a DCE that receives clock from its own network source (e.g., a T1MUX or DSU that is on the DDS network).Disab — Select disable if you do not have an extended network or are providing the clock source to the extendednetwork (e.g., LADS with external clock).RxElasStor: DisabNext Enab Disab PrevReceive Elastic Store (only displayed when Full Mode is enabled). The DBM receives data using a receive data bufferon the DBM’s received data (RXD) lead. This configuration option only supports single-port DBMs configured fordisruptive diagnostics (Diag Type is set to Disr) and no rate adaption – whenRate(Kbps) is equal toPrtSp(Kbps). Boththe control and tributary DBMs must be configured the same.Enab — Select enable when interfacing with a DCE that receives clock from its own network source and does notsupport a Transmit Elastic Store.Disab — Select disable if you do not have an extended network.
