COMSPHERE 3600 Series Data Service Units
Disr Type: 3600e
Next 2500 2600
Disruptive Diagnostic Type. Defines the diagnostic interaction between the control and tributary DSUs. It must be set
consistently for all DSUs on the same circuit when Diag Type is set to Disr, NonD, or Mixed. Regardless of the diagnostic
type enabled, aggregate tests are still sent disruptively.
NOTE: If the DSU Rate(Kbps) is set to 64CC, the DSU defaults to Disr Type 3600e and no other configuration options
will appear for this configuration option set.
2500 – Only for point-to-point circuits when the control is either a 2500 or 3500 Series DSU, or the tributary is a
2500 Series DSU. Digital Loopback and Digital Test commands are sent using the 2500 signaling. All other remote
commands use 2600 signaling. When 2500 is selected and AutoRestor is enabled, RespondRDL (Table 4-4) must be
enabled for automatic restoration to work.
2600 – Used in mixed networks when the control is a 2600 Series DSU and the tributaries are 2600/3500/3600 Series
DSUs, or when the control is a 3600 Series DSU and at least one tributary is a 2600 or 3500 Series DSU. This selection
is not available for digital DBMs.

3600s – Used in circuits containing only 3600 Series DSUs. This configuration option performs full 3600 diagnostics
between control and tributary DSUs. It utilizes Switched CMI/DMI mode (control mode idle/data mode idle) signaling to
ensure protocol independence with primary data and to trap diagnostic messages in DSUs. It is recommended that this
mode be used when the control and tributary DSUs are configured for RTS Cntrl: FrcOn (Table 4-4). Switched-carrier
operation can be supported; Msg Clamp (Table 4-1) must be disabled. This selection is host protocol independent, but
not as fast as 3600e described below. This selection is not available for digital DBMs.
3600e – An alternate diagnostic protocol for circuits containing only 3600 Series DSUs. It is the diagnostic type protocol
used on 64 kbps CC and backup PSTN links. This configuration option performs full 3600 diagnostics between control
and tributary DSUs. An escape mode signaling (special data pattern) is utilized for minimum disruptive effect, or when
the network does not support CMI network codes.
Br56 – Required for aggregate switching and digital bridge configurations when a Switched 56 DBM or ISDN DBM is
installed.

Do not use 3600s if you have a point-to-point tributary with disruptive diagnostics, no rate adaption, and
RTS configured with DTE.
