3610 User Manual

COMSPHERE 3600 Series Data Service Units
Multiple sets of factory defaults: Provides several
full sets of default configuration options in DSU
memory for:
— Control (FacC)
— Tributary (FacT)
— Central-Site Digital Bridge (FacB)
— Multipoint Control (MPTC)
— Multipoint Tributary (MPTT)
Options sets can be saved to several storage areas.
Front panel control: Provides control from a front
panel with a 2-line, 16-character liquid crystal
display (LCD), light-emitting diode (LED) status
indicators, and software-defined function keys.
— Model 3610 has a front panel
— Model 3611 has a shared diagnostic control
panel (SDCP), which is mounted on the
COMSPHERE 3000 Series Carrier. The SDCP
can be shared by as many as 128 DSUs
Either front panel provides:
— Health and Status information
— Modifiable configuration options
— Initiation of tests and commands
— Reports of test results
— Management of remote DSUs
Network interface (aggregate): Provides an
additional mode of dial backup. When Network
Interface is set to aggregate switch or forced on, the
DSU provides an internal aggregate data stream,
including diagnostics, framing, and standby mode
on the alternate V.35 or EIA-232 interface of Port 1.
Full tributary diagnostics: Supports an enhanced
set of diagnostic tests and commands. The set of
diagnostics can be addressed to tributaries from:
— A COMSPHERE 6700 or 6800 Series NMS
workstation
— The front panel
— The async terminal of a control DSU
— A DATAPHONE II System Controller or
Network Controller
1-2
Point-to-Point and Multipoint: Supports both link
configuration options.
Async terminal control: Provides control from an
async (asynchronous) VT100-compatible terminal.
This feature is available only for a Model 3610
standalone DSU.
External dial backup: Provided by an external
dial backup unit (DBU), such as a 3800 Series
dial/lease modem, for a point-to-point DSU.
SNA Diagnostic Interface: The 3600 Series DSU
has SNA (System Network Architecture)
Diagnostic Interface with the LPDA-2 protocol
installed on the circuit card. LPDA-2 (Link
Problem Determination Aid, Release 2) diagnostics
are part of IBM's NetView management system.
When enabled, the SNA Diagnostic Interface
provides the following features:
— LPDA-2 protocol, allowing the 3600 Series
DSU to be controlled from IBM's NetView
management program.
— Full option support for all other 3600 Series
DSU options, including Dial backup module
(DBM), Time division multiplexer (TDM), and
Multichannel multipoint (MCMP).
— With TDM/MCMP, Port 1 supports LPDA-2.
For digital sharing, LPDA-2 support is
available on all ports.
