The Patton T1/E1 Digital Cross Connect (DACS) series of products makes
cross-connection applications simple and affordable, and most importantly,
by offering models with 4, 8, and 16 T1/E1 ports, a growth path for future
Using a robust hardware platform and a rich set of software features
including a intuitive graphical SNMP/HTTP user interface, the DACS series
can be used in a series of applications ranging from non-blocking cross
connection, to multiplexing, to transport of E1 over T1 lines, or vice
When enterprise growth includes the use of multiple E1 or T1 lines, the
Model 2604, DACS are the ideal tool for managing and maximizing the
allocation of 64kbps channel in under utilized lines, reducing the cost
per channel and freeing bandwidth for further growth. Enterprise customers
can concentrate data and voice services from local sub T1 and E1 lines
onto fully utilized local loop uplink connections with complete freedom
and ease of use.
The Model 2604 features an RS-232 and a 10/100Base-T port configuration.
The RS-232 port provides access to VT-100 configuration menus, while the
10/100Base-T port allows remote configuration and monitoring via Internet
connection from any location in the world. For remote configuration the
Model 2604 comes with a built-in web server, which provides intuitive drop
down menus for simple configuration testing and monitoring. For complete
flexibility, The Model 2604 can also be managed using any standard SNMP
The Model 2604 comes in a slick 1U high, 19 in. wide chassis for
convenient installation on standard telco racks. RJ48C connectors provide
standard T1 and E1 interfaces to network and local lines, while compact
RS-232 Console and 10/100Base-T ports allow complete command and control
of local and remote units. Dual redundant powers supplies, with choices of
DC or AC inputs, assure uninterrupted operation and service. Front panel
LEDs provide at-a-glance status of system and network signals, while a
comprehensive set of diagnostics features and alarms enable network
personnel to quickly isolate failures and minimize down time.
The Model 2604 series of DACs products can also be used in conjunction
with Patton DSL, T1/E1 NTUs, fiber optics T1/E1 multiplexers, and network
extenders, etc to provide a complete geographical solution to enterprise
costumers in wide area network deployments.
Aggregation. Medium-size enterprises can aggregate and groom time
slots from up to three partially used local T1/E1 lines onto a single
outgoing link. This capability enables routers, PBXs, and other
network devices dispersed over the campus area to efficiently use a
single T1/E1 line for network access.
Conversion. In situations where T1 and E1 networks converge, ports
on the Model 2604 can be configured as E1 or T1 interfaces. This
feature provides the capability for mapping and transparently
transport T1 64 kbps time slots over E1 lines, and up to 24 E1
channels per T1 line.
Area Deployment—Local Switching. In a wide area deployment,
medium- and large-size enterprises can use the Model 2604 for local
timeslot switching from multiple local or remote T1/E1 lines. The
model 2604 HTTP/SNMP flexible management allows provisioning and
monitoring of switching sites from any remote or central location.
2604 HTTP/SNMP Configuration Management Screens
Point-and-click HTTP management menus offer customers the simplest way to
configure and monitor the Model 2604.
DS0 Mapping screens display a colorful grid of ports and 64kbps channels,
simply click and drag timeslots from a port to any other port within the
grid and the connection will be completed transparently by the 2604.
Channels that have active connections appear in green, inactive channels
in red…it doesn’t get any simpler than this. Additionally, for those who
prefer to enter command line type configuration, the 2604 offers the
option to switch to command line screens.
T1/E1 configuration screens, offers line configuration by intuitive drop
down menus, while the T1/E1 link activity page offer per link status
information, current and historical near and far end line statistics, and
alarm configuration… all at the click of a mouse.
For greater flexibility, the 2604 management software also allows
configuration and monitoring via third party, industry standard SNMP
