T1 - Frame Relay Access Probe
(T-FRAP) Overview
The Sync T-FRAP is a Frame Relay Access Probe with an embedded SNMP agent and
T1/FT1 DSU/CSU. Part of the Sync family of FRAP devices, the T-FRAP offers
advanced in-band management which allows the device to be SNMP-managed remotely
without the use of an external SLIP, PPP or LAN connection. This eliminates
router dependency and management cables and it improves reliability.
The T-FRAP independently monitors the frame relay network and provides
valuable network performance statistics on frame relay traffic as well as the
ability to trend application protocol usage for adjustable, local unit
collection periods.
Features:
- Collects information on frame relay environments such as DE, FECN/BECN,
LMI and more
- Monitors performance of SNA, IP, IPX and other transport protocols and
tracks application usage by socket protocols, such as HTTP, SMTP and many
others, using the Pro-Act software module
- Pro-Act module maintains statistics locally on the T-FRAP for up to 4
days, reducing polling activity
- VT-100/TELNET access and PING support
- TFTP software downloadable over the network
- Five year warranty
BENEFITS
Every frame relay network that employs T-FRAP technology will experience
substantial benefits:
- calibrate network resources to fit application requirements – this reduces
network operating costs
- minimize network downtime by anticipating and pinpointing problems before
they strike – this prevents costly network outages and maximizes network
availability
- minimize technical support personnel needed by providing effective, but
simple-to-use management tools – this saves labor costs and maximizes
productivity
- optimize application of network resources and improve network availability
with comprehensive information for network planning – this maximizes business
revenues
Applications:
- The T-FRAP can be used at the central site to provide frame relay access
for routers and Frame Relay Access Devices (FRADs) and to monitor traffic and
provide statistics on the frame relay network.
- The T-FRAP can be used for monitoring T1/FT1 remote sites.
- The T-FRAP collects and routes network management data back to the central
site without requiring local LAN access.
Trend Analysis and Circuit Management
- The T-FRAP gathers frame relay statistics which provide vital network
utilization information for both end users and carriers. These statistics,
used independently or in conjunction with Sync Performance Manager, produce
graphics-based trending reports, enabling network managers to analyze network
performance over time, calibrate bandwidth and pinpoint potential problem
sources before they affect users.
VNIP Provides Troubleshooting Tools for Virtual Networks
- Sync’s Virtual Network Interactive Protocol (VNIP) is a software protocol
that enables network operators to gain visibility of their virtual network to
ease troubleshooting and network planning and to ensure quality of service.
While virtual topologies, such as frame relay, result in significant cost
savings, the traditional, point-to-point network troubleshooting tools are no
longer available. VNIP architecture gives T-FRAP users visibility into the
network "cloud" to automatically discover end-points and potentially provide
other valuable services such as network latency delay measurement and logical
per PVC loopbacks.
Advanced In-Band Management
The Sync T-FRAP provides five SNMP access methods:
- Piggyback (In-Band Injection) – injects management packets into data
stream during quiet traffic periods. It is designed to deliver SNMP
information without adding a significant network latency burden. Requires no
cables and is independent of the router. It even continues to deliver
information should the router fail.
- Local Data Link Connection Identifier (DLCI) – a private DLCI provisioned
between the router and the T-FRAP allows the exchange of SNMP traffic. The
local DLCI configuration provides a cost-effective management solution without
the use of SLIP, PPP or costly LAN attachment methods at no extra cost to the
user.
- Remote DLCI – allows a central site or carrier NOC to monitor the remote
T-FRAP via a separate management PVC without passing through the remote
router.
- Bi-directional – local and remote DLCI methods enabled simultaneously;
allows both carrier and customer to examine information collected by the
T-FRAP.
- SLIP – allows operators access via SNMP or TELNET using an optional SLIP
connection if desired.
