Ext Leads: Rate
Next ExtLd Rate
External Leads. Controls the use of the general-purpose leads on the EIA-232-D/V.24 interface for Port 1 except when
Rate is selected. These leads can be controlled and monitored from the front panel, an async terminal, or a 6700 or
6800 Series NMS.
ExtLd – Enables Pins 12 and 13 as output (control) and Pins 19 and 23 as input (alarm) leads. When enabled, Pins 12
and 13 output +12V when ON and –12V when Off. Pins 19 and 23 recognize voltages from +2.2V to +12V as ON
(reported as an External alarm) and –12V to +.8V as Off.
Rate – If the TDM or MCMP option is installed, use Pin 12 on each port to control speed selection and make an
extended modem change speed to match the backup port speed. Pin 12 on all ports turns Off at the same time to
indicate that the TDM is in fallback. If a port does not fall back and remain at the same speed, then the fallback feature in
the DCE connected to that port should not be enabled.
RPowr – Functions similarly to ExtLd, but the inputs report power failure or fan alarms when a redundant power supply
is installed in the COMSPHERE 3000 Series Carrier.
CCN by EL: Disab
Next Enab Disab
Configuration Change Notification by External Leads. Controls the use of the general-purpose output leads to set an
CCN event. This configuration option only has an effect if Ext Leads is set to ExtLd and the protocol is ADp.
Enab – Change in state of a general-purpose lead signals CCN to the NMS.
Disab – General-purpose lead changes do not set a CCN event.
DTR Alarm: Disab
Next Enab Disab
Data Terminal Ready Alarm. Causes the DSU to generate an alarm if DTR is Off for more than 30 seconds. The front
panel or async terminal displays DTR Alarm and reports it to the NMS. Does not appear for TDM or MCMP mode.
Enab – If DTR lead turns Off for 30 seconds, the DSU generates an alarm.
Disab – No alarm is generated when DTR lead is Off.
SW Vers: Normal
Next 3.24 4.43
Software Version of the DSU. Forces the DSU's software/firmware version to be reported to the NMS through the
Identity (ID) command in the DSU SW vers field. This configuration option supports NMS compatibility for a tributary
DSU with a control DSU with an older software version. It applies when Diag Type is set to Disr (Table 4-2) or when a
multipoint DSU configured for Mixed or NonD diagnostics is not operating in MCMP mode.
When the control DSU's software version is 7.25 or greater, it will be compatible with any tributary 3600 Series DSU,
regardless of its software version. To ensure optimal functioning of the DSU, both the control and tributary DSU's SW
Vers configuration option must be set to Normal, and the tributary DSU's set to Normal or No.
NOTE: Refer to Firmware Version Control, Table G-1.
If the control DSU's software version is less than 7.25, the following configuration option changes need to be made:
3.24 – Set 3.24 for a tributary DSU when the control DSU's software version is 3.13 or less, and the tributary DSU's
software version is 5.15 or greater. No setting change is required for the control DSU; the DSU SW Vers configuration
option is not available to the control.
4.43 – Set 4.43 for the tributary DSU when the control DSU's software version is 4.25 or 4.28 and the tributary DSU's
software version is 5.15 or greater. For the control DSU, set the 3.20 DSU SW Vers (the name of the configuration option
in an older firmware version) configuration option to No.
6.66 – Set 6.66 for the tributary DSU when the control DSU's software version is 6.xx or greater and the tributary DSU's
software version is 8.xx or greater.
Normal – Select Normal for both the tributary and control when both DSU software versions are 7.25 or greater.
