The TyLink 3250
is a single-port T1/FT1 DSU/CSU with an integral SNMP
agent which can be accessed via SLIP or Ethernet attachment.
Offering the industry’s
most cost-effective SNMP-managed DSU/CSU solution, the
TyLink 3250 connects LAN routers, CDPD (wireless) equipment,
video codecs and other digital devices to the wide area
network.
The TyLink 3250 provides flexible management capabilities:
it can be managed through an ASCII terminal, through SNMP
via a built-in SNMP agent and SLIP port or Ethernet attachment,
or via TELNET. All TyLink 3250 capabilities available through
the terminal interface can also be accessed via SNMP, including
complete support for GETs, SETs and TRAPs. The TyLink 3250
accepts new software loads locally or from a remote site
via a modem, which reduces maintenance costs by eliminating
the need for remote site visits to update the product.
Extensive Performance
Monitoring Information
The TyLink 3250 monitors the performance of the network
in fifteen minute increments and maintains a twenty-four
hour history of performance monitoring information. This
information includes:
- CRC-6 errors
- Out of frame events
- Error events
- Errored seconds*
- Severely errored seconds*
- Failed signal state
- Failed seconds*
- Bipolar violations*
- Bursty errored seconds
*saved as historical data in 96 sets of 15 minute intervals

Benefits
The TyLink 3250 provides the following benefits:
- full range of features allows flexible access for frame
relay as well as standard digital networks - this allows
standardization and ease of use in many different applications
- operates in a wide range of management environments
via a variety of access methods independent of the type
of router - this allows users to standardize on one product,
saving installation time and maximizing investment
- plentiful and flexible diagnostics and robust performance
monitoring capabilities enable timely resolution of network
problems - this maximizes network uptime
Applications
The TyLink 3250 is used in point-to-point
T1 or FT1 applications to provide frame relay and digital
network access for routers and other digital devices, including
CDPD (wireless) equipment and video codecs.
The TyLink 3250 can also aggregate remote site traffic
from 56 Kbps devices, such as the Tylink 1250, onto one
T1 circuit.
Flexible Management Capabilities
The Tylink
3250 supports a variety of management methods including
a VT-100 interface with access via TELNET or ASCII terminal
or modem, and an integral SNMP agent that can be accessed
via a SLIP port or optional Ethernet attachment. These
methods allow management through all types of digital networks,
including frame relay. A complete implementation of SNMP
is provided with the TyLink 3250 including GETs, SETs and
TRAPs as well as standard MIBs and MIB extensions.
