GDC NMS 510 Series
Adaptive Universal Rate Diagnostic
Data Service Unit
| Product Highlights
• Adapts to network service type for support of
conventional digital service or networks with secondary channel
• Automatically adjusts to universal data
rates 2.4, 4.8, 9.6, 19.2 and 56 kbps, for improved responsiveness and ease
of upgrades as your applications expand
• Supports integral, single-call dial backup
restoral with leased line loopback for continuous communications around
failed circuits
• Intelligent Front Panel option provides
for the installation and programming of units
Product Description
Besides providing a universal data rate capability for 2.4, 4.8,
9.6, 19.2, 56 and 64 kbps, the NMS 510 Series automatically adapts to the
speed of the network as required by your application. In particular, this
ensures a cost-effective migration path for those seeking to upgrade speeds
in the future. An optional data rate adapter permits subrate terminal
equipment to operate on 56 and 64 kbps aggregate circuits. This unique
adapter functions point-to-point or multipoint at 56 kbps only.
The NMS 510 Series is available and
interchangable in standalone or rackmount enclosures. The rackmount assembly
accommodates a variety of data communications products, including up to 16
NMS 510s, in the same high density rack. The units are well suited to these
installations because of extremely low power consumption and resulting low
heat generation, promoting longer component life and higher reliability.
Integral Dial Backup
Single-call dial restoral over the switched network takes place
through an optional DBU-89 dial backup unit. The DBU-89 provides a full
duplex, primary channel at up to 14,400 bps. This implementation reduces the
number of circuits needed for restoral of critical network links. Dial
backup is initiated from the central site without remote site
intervention. Also included is a leased line lookback feature that monitors
the primary digital circuit and re-establishes communications over this
facility once it has been repaired.
Intelligent Front
Panel
The NMS 510 can be ordered with an Intelligent Front Panel (IFP)
option to ease installation of the units, particularly at remote sites. An
NMS 510 with the IFP may be used to program and monitor any other NMS 510
IFP or standard front panel unit, either locally or through downline-loading.
Many basic management routines are supported, including: soft-strapping,
status display, monitoring line parameters and EIA leads, plus diagnostic
testing. A 2-line by 16-character LCD display and a series of 4 buttons on
the front panel allow you to step easily through English language,
menu-driven programs that simplify the process of setting up new network
circuits.
