COMSPHERE 3600 Series Data Service Units
DTRCallCon:Disab
Next Orig Ansr
Data Terminal Ready Call Control . Used in conjunction with the Primary Core configuration option (Primary
Core set to Yes). DTRCallCon uses the state of the DTR lead to control backup when contact with the
remote DSU is lost. When set to Orig, the DBM originates a backup call when DTR is raised. When set to
Ansr, the DBM only answers a backup call when DTR is active. The DTR lead is ignored when DTRCallCon
is disabled.
Orig — DTR lead is used for outgoing calls. When Primary Core is set to Yes and Orig is selected, the
DBM originates (dials out) a backup call when DTR is raised based upon the number stored in
the Backup Directory specified by the Backup Dir configuration option, and drops the call when
DTR goes low. If Multicall is also enabled, the multiple calling cycle is used (refer to
Orig is only displayed when Primary Core is set to Yes.
Ansr — DTR lead is used for incoming calls. When Primary Core is set to Yes and Ansr is selected, the
DBM answers a backup call from the remote DBM when DTR is raised. It drops the call when
DTR goes low or will not answer an incoming call if DTR is low.
Disab — Disables DTR Call Control; the state of the DTR lead is ignored.
EchoCancel:Disab
Next Enab Disab
Echo Cancel . This configuration option is only displayed for a Switched 56 DBM and is required if the
switched 56 kbps network is US SPRINTr or when the network has echo cancellers. Disable this
configuration option if the DBM is interfaced to an AT&T switched 56 kbps 4-wire service facility.
Enab — Enables Echo Cancel.
Disab — Disables Echo Cancel.
Remot DBM:4-wire
Next 2-wire 4-wire
Remote Dial Backup Module . Specifies the identity of the far-end Switched 56 DBM so the appropriate dial
backup process completion time can be determined. This configuration option only appears for a 2-wire
Switched 56 DBM with EchoCancel enabled. If unsure of whether the remote DBM is 2-wire or 4-wire,
select 4-wire.
2-wire — Originating remote DBM is a 2-wire Switched 56 DBM, so the process completes in
460 milliseconds.
4-wire — Originating remote DBM is a 4-wire Switched 56 DBM, so the process completes in
3.85 seconds.
