Diagnostic General Configuration Options
Position: Trib
Next Cntrl Trib G2Trb Prev
Network Position. Determines the DSU’s position in the network, and defines its test and diagnostic capabilities. In
Bridge mode, the only value available is Cntrl.
Cntrl – Control. Digital bridge must be set to Cntrl.
Trib – Tributary.
G2Trb – This selection appears only in a DPII protocol mode. In a DATAPHONE II network, configure the outbound
tributary as a G2Trb and have one DSU on its poll list. Configure other tributaries as Trib.
LinkConfig: Pt-Pt
Next Pt-Pt M-Pt Prev
Link Configuration. Determines a point-to-point or multipoint circuit. This configuration option is required for proper
operation, testing, dial backup procedures, and nondisruptive diagnostics.
NOTE: For a DSU loaded from FacB, or a DSU with MCMP installed and loaded from FacT or FacC, the default is
M-Pt (multipoint).
Pt-Pt – Point-to-point configuration.
M-Pt
– Multipoint configuration.
Resp Period: 1
Next 1 2 10 Prev
Response Period. Determines how frequently the DSU sends health and status information. This applies to RTS/CTS
Delay diagnostics, which is used for single-port multipoint configuration if the Diagnostic Type configuration option is set
to NonD or Mixed (Table 4-2). Although this configuration option determines how often the health and status message is
transmitted, an extended RTS/CTS delay occurs each time the DTE raises or lowers RTS. Applicable to tributary DSUs
and DBMs only.
1 – Tributary DSU responds with health and status information each time the DTE raises RTS.
2 – Tributary DSU responds with health and status information every other time the DTE raises RTS.
10
–
Tributary DSU responds with health and status information every tenth time the DTE raises RTS.
TribTimOut: 0:10
Next Chang Prev
Tributary Time-out. The time (in minutes and seconds) that a DSU waits for a tributary health and status report before
generating a T
ributary Time-out alarm. This setting can be from 5 seconds to 10 minutes. Use this configuration option
for single-port multipoint configurations when the Diagnostic Type is set to NonD or Mixed (Table 4-2).
Chang – Set this configuration option to greater than or equal to the maximum amount of time it takes for the front-end
processor (FEP) to complete its polling cycle on that circuit, multiplied by the value entered in Resp Period.
Diag Conn: CC
Next CC DC Prev
Diagnostic Connection. Set this value to match the connection set up for the 3600 Hubbing Device connected to this
DSU. Refer to the
Network Diagnostic Connection
section in Chapter 2. This configuration option is only available for a
Model 3610 DSU configured as a control.
CC – Control Channel. Set Control Channel for CC IN/DC OUT connection as the first link an NMS.
DC – Diagnostic Channel. Set Diagnostic Channel for CC OUT/DC IN connections from the remaining tributaries.
