1 Product Description
1.1 Description
The Loop-IP6610 Router provides connectivity from 10/100 BaseT to E1, DS1, DTE, or DCE interface in a
small metal box. This unit is a low cost access router with an E1/FE1(or DS1/FDS1) line interface and a
10/100 Ethernet interface.
The Loop-IP6610 supports multiple routing protocol including static route, RIP I, RIP II, and multiple WAN
link layer protocol including PPP and HDLC. It is perfect for small and medium sized businesses (SMBs)
using it as an access WAN router. The Loop-IP 6610 integrates E1/DS1 CSU/DSU and an optional built-in
single port Ethernet switch to provide cost effective access solution for SMBs or branch offices. It also
supports a user-friendly Command Line Interface (CLI), an SNMP management interface and user-friendly
web management.
The Loop-IP6610 Router supports a DB9S console port, which allows users to execute in-service
diagnostics and fault isolation from a local or remote terminal. The Loop-IP6610 Router also allows remote
site to Telnet communication via the Ethernet port or the WAN port. The IP6610 Router provides
multicolored LED indicators on the front panel and an ACO (Alarm Cut-Off) button.

2 Loop-IP6610 Installation
2.1 Site Selection
The following list indicates a site selection guideline. Users need to follow this guideline to select a proper
installation site.
1. Location of the Loop-IP 6610unit should be part of the central office equipment layout design.
Consideration should be given to entrance cable routing.
2. The installation site should provide proper room for adequate ventilation and cable routing. Reserve at
least 0.5 m at the rear of the unit for human access, cables, and air flow.
3. The site should provide a stable environment. The operating area should be clean and free from
extremes of temperature, humidity, shock, and vibration.
4. Relative humidity should stay between 0 and 95%.
2.2 Mechanical Installation
The Loop-IP 6610 is designed to be used as a desktop unit.
2.2.1 Desktop Installation.
For proper desktop installation work through the sequence of events below in the order that they appear.
2.2.1.1 Chassis Grounding
For stand alone units a dedicated chassis ground screw and lock washer is provided. The chassis ground
screw is located on the right side of the rear panel.
When attaching a ground wire to the chassis ground screw, please follow these instructions.
 Use copper grounding conductors of 18 AWG
 Conductors should not be of dissimilar metals.
 The bare conductors should be coated with anti-oxidant before crimp connections are made.
 Any unplated connection surfaces, connectors, braided strap and bus bars must be bought to a bright
finish and coated with anti-oxidant before connections are made.
CAUTION:
 Never install telephone wiring during a lightning storm.
 Never install telephone jacks in wet locations unless the jack is specifically
designed for wet locations.
 Never touch un-insulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
 Use caution when installing or modifying telephone lines.

2.2.1.2 Power
The power connection on your unit will be either AC 100-240V or DC 20-60V. An optional DC 36-75V power
connection is also available. Before attaching any power supply, check the label on the rear of the Loop-IP
6610 unit to ensure that you connect the unit to the correct power source. The power switch at the rear of
the unit should be in the OFF position while you connect the power source. See Section 2.5, Rear Panel
Connectors and Switch.
Caution: Do not (under any circumstances) connect the Loop-IP unit to a power source that
is inconsistent with the power rating that is labeled on the rear of the Loop device.
2.2.1.3 Line Connections
You can now make your line and Ethernet connections.
Step 1 Connect the Loop-IP 6610 to a LAN
Connect the LAN to the 10/100 Ethernet port of the IP 6610. Because the Loop-IP 6610 supports MDI/MDI-
X auto crossover, you can use either a parallel or a crossover cable to make the connection.
Step 2 Connect the E1/DS1 Line to the Loop-IP 6610
If you are using a RJ48 (E1/DS1) line connector, plug it into the IP 6610’s RJ 48 receptacle. If you are
using BNC (E1)connectors, plug them in. The BNC receptacles on the IP 6610 are clearly labeled RX-IN
and TX-OUT.

2.3 Front Panel Console Port and LEDS
The Loop-IP6610 is a stackable desktop unit. The front and rear panels are shown in the following figures.
The LEDs on the front panel indicate unit performance. The console port provides access for a VT-100
monitor for unit setup.

The Loop-IP6610 DTE Front Panels are shown in the following figures.
Figure 2-2 Loop-IP6610 DTE Front Panel (Four Ethernet)
Figure 2-3 Loop-IP6610 DTE Front Panel (Single Ethernet)
There are six DTE and one DCT options available. They are: V.35, V.36, RS232, EIA530, X.21 and RS422
for DTE interface, and one V.35 for DCE interface. Each of these options is available in AC 1 Port, AC 4
Port, DC 1 Port and DC 4 Port versions.
The sample illustration from Figure 2-4 to 2-7 below depicts the rear panel views for the EIA530 DTE
option. The rear panel views for the other DTE/DCE options are similar.

2.4 Console Port
To use the RS232 interface to configure the unit, use a straight cable to connect a VDS100 terminal to the
DB9 jack (Console Port) on the front panel of the Loop-IP6610. The VDS100 terminal can be a PC running
VDS100 emulator software. The unit is configured as a DCE.
