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.
Configuration and Features
Is the Model 2701 series available in rack card and standalone versions?
Yes, the 2701 is offered in a compact standalone unit, as well as 2U-high rack cards for
the 1001 NetLink system.
How is the 2701 different from Patton’s Models 2703 and 2707?
The Model 2701 is an E1 unit that operates in standard framed and unframed modes.
In framed (G.704) mode the Model 2701 series provides nx64kbps rate an interface
conversion. In G.703 mode the 2701 series connect to terminals at 2.048Mbps.

FAQs
On the other hand, The Models 2703 and 2707 operate in unframed mode (G.703) only
connecting to the network and terminals at 2.048Mbps.
How is the 2701 configured?
The Model 2701 is configured via DIP- switches located on the underside of the unit.
Additionally rack cards are configured and managed via VT-100 terminals using a
1001CC card, or SNMP/HTTP by using a Model 1001MC proxy card.
Model Configuration Options
2701 Standalone Switches
2701RC Rack Card Switches, VT-100, and SNMP/HTTP
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.
What Clock Modes are supported?
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.
How are timeslots (channels) selected in the 2701 series?
The 2701 standalone offers switch configuration only, timeslots are selected
contiguously, starting at timeslot one. Rack cards, when managed via VT-100 or SNMP,
offer the user flexibility to select timeslots contiguously or non-contiguously, starting at
any timeslot.

What DTE interfaces does the 2701 series support?
The Model 2701 supports single DTE interfaces and comes in four versions: V.35 (M34
connector), X.21 (DB-15 connector), EIA-530 (DB-25F), and 10Base-T (RJ-45
connector). See table above for interface options.
Do I need special cables to connect to the 2701 Series?
No, the 2701 is equipped with industry standard interfaces, saving the user
the extra cost associated with non-standard cables. The V.35 version uses a
female M/34 (Winchester) connector. The Model X.21 version, uses a female
DB-15 connector, and can be configured as DCE or DTE. The 10Base-T
version uses a standard RJ-45F connector.
Can the serial interfaces be configured as DTE or DCE?
The X.21 interface can be configured as DTE or DCE; the V.35 and EIA-530 interfaces
are fixed as DCE. 10Base-T Ethernet interfaces are wired as DTE for direct connection
to a hub/switch.
Does the 2701 ship with terminal and network cables?
No, the 2701 ships with user’s manual and power supply (standalone), no terminal or
network cables are included.
What diagnostics are offered with the 2701?
