Model 2701 and 2701RC Series Frequently Asked Questions
Applications
What are the applications for the Model 2701 Series?
Access for Point-to-Point Digital Leased Lines
Enabling the enterprise customer to cost effectively connect their routers, multiplexers,
or PBXs to central or remote sites using Clear Channel or G.704 services.
Dedicated Internet Access. An ISP
uses E1 to deliver high speed Internet
traffic from a Point-of-Presence (POP)
to a customer premise. An NTU is
used at each end of the link and
converts the E1 to a serial interface
format for use by a router or
multiplexer.
LAN-to-LAN Bridging - The Model
2701/I connects remote LANs using standardized G.703 services. A 2701/I is placed at
a remote location and another 2701/I, or a router, at a central location. Using RRP
(Remote Router Porting), which combines the technology of bridging, with PPP for
standards based transport, with a router configuration to offer a routed network
connection with only one router.

What is required for rack card SNMP Management?
The Patton’s 1001 rack system allows SNMP management of Models 2707RC and
2701RC, or xDSL cards via the Model 1001MC management card. The Model 1001MC
connects to an Ethernet LAN, and can be accessed through the Internet from any
location in the world. Up to 13 2701RC cards can be managed per rack, and a total of
120 cards can be managed cascading racks with a single 1001MC card and 1001CC
control cards.

Internal, External, and Network Clock. The Model 2701 series of products are factory
configured for network clock used in most G.703 field applications.
What Line Coding Options Does the Model 2701 series support?
The Model 2701 Series support AMI (Alternate Mark Inversion) and HDB3 (High Density
Bipolar of Order 3) line codes. Generally, E1 G.703/G.7-04 services use HDB3 Line
coding. The 2701 series is default configured for HDB3 line coding at the factory.
Does the Model 2701 support framed G.703 (G.704)?
The Model 2701 series are G.703/G.704 units, as such they can terminate framed and
unframed E1 services. If only unframed G.703 is needed, use the models 2703 or 2707.
