Upstream Port. If an extended control DSU has its DTE interface connected to the tributary DSU or APL modem and the
configuration option Extend Chan is set to Yes, set this configuration option to the upstream port number. Select Prt1 if
the tributary DSU is operating in single-port mode. This configuration option has an effect only if Diag Type is set to
NonD.
Prt1 to Prt6 – Selects the upstream port number.

Multipoint Symmetrical Port. This configuration option enables rate adaption in the tributary DSU to control direction on a
multipoint circuit. This configuration option will not appear for a point-to-point circuit or when operating in MCMP mode.
Enable this configuration option:
When performing multipoint rate adaption (e.g., the port speed is less than the line speed), or
If the transmit data rate is required to match the receive data rate for single-port multipoint nondisruptive
diagnostics
This is generally the case in extended circuit applications and in multipoint applications where the tributary DSU is
configured as a digital-sharing device.
NOTE: Enable this configuration option for the control DSU and the tributaries; the control DSU and tributaries must be
set the same.
Enab – Enable this configuration option when performing multipoint rate adaption or when a multipoint network is
configured for nondisruptive diagnostics and a symmetric port speed is required for proper DTE operation.
Disab – Disables multipoint rate adaption on data from the tributary to the control DSU (asymmetrical).
Fast Sel: Enab

Fast Select. Fast Select is a technique used by ADp protocol or the 6700 or 6800 Series NMS. When enabled, the DSU
transfers a message to a downstream device in a character-by-character format. When disabled, the DSU transfers the
message to the downstream device in packet or block format. The 3800 Series Dial Modem does not support Fast
Select; therefore, you must disable Fast Select in all 3600 Series DSUs between an NMS and a 3800 Series Dial Modem
on an extended circuit.
This configuration option does not appear if the DSU is a multipoint single-port device, if the protocol used is DPII, or if
Diag Type is set to Disr or None.
Enab – Enables the Fast Select feature.
Disab – Disables the Fast Select feature. When disabled, all devices on the same level of the circuit must be disabled.

When in MCMP or TDM mode, this configuration option does not appear. Instead, it is displayed in the DSU Port
Speed configuration options for MCMP or TDM under Port 1. Ports 2 – 6 must be set independently.
