ETH1 / ETH2— Ethernet connection port. These ports support both device management and payload
data transport. Depending on ordered options, the unit may have one or two Ethernet ports. This is a
standard RJ-45 jack and features MDIX auto-sensing capability, allowing straight-through or crossover
cables to be used.
Connecting to the unit via SSH supports device management and provides the same user interface
available using the unit’s COM1 serial port. Various options are available for passing Ethernet data,
allowing system administrators to optimize the configuration for maximum efficiency, based on the
system’s operating characteristics.
(As viewed from the outside the unit)
USB Port—This port allows for connection of a laptop or PC. The port provides a local console for
management of the device. A standard host-to-mini device USB 2.0 cable may be used.
COM1/COM2 Port—This connector serves as the serial interface port for both console management and
payload data. Depending on ordered options, the unit may have one or two COM ports. By default, the
port is enabled for local console control. The COM port serves as the primary interface for connecting the
unit to an external DTE serial device supporting RS-232 or RS-485. If necessary, an adapter may be used
to convert the unit’s RJ-45 serial jack to a DB-9F type (GE MDS 73-2434A25).
NOTE Not all PCs include a serial port. If one is not available, the unit’s USB port may be used to
access the device management interface. Alternatively, a PC’s USB port may be used with a
USB-to-Serial adapter and appropriate driver software. These devices are available from several
manufacturers. A video covering USB driver installation may be accessed from the following
link: http://tinyurl.com/pey2ull
The COM port supports a serial data rate of 1200-230400 bps (115200 default, asynchronous only). The

2.6 Grounding Considerations
To minimize the chance of damage to the unit and its connected equipment, a safety ground (NEC Class 2
compliant) is recommended, which bonds the chassis, antenna system(s), power supply and connected
data equipment to a single-point ground, keeping all ground leads as short as possible.
28 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G

surface. If the unit is not mounted to a grounded surface, it is recommended that a safety ground wire be
attached to the screw provided on the bottom corner of the enclosure, in the recessed flat area.
Alternatively, a safety ground wire may be attached to one of the mounting bracket screws.
The use of a lightning protector is recommended where the antenna cable enters the building; Bond the
protector to the tower ground, if possible. All grounds and cabling must comply with applicable codes
and regulations. One source for lightning protection products may be found online at
http://www.protectiongroup.com/PolyPhaser.
2.7 Mounting Options
The unit may be mounted with flat mounting brackets or an optional 35 mm DIN rail attachment. Figure
2-7 shows the mounting dimensions for a unit equipped with flat mounting brackets.

2.8 Antenna Planning and Installation
Consideration must be taken to select appropriate antennas for optimal RF performance. This section
reviews the key factors involved in selecting and installing antennas for the Orbit MCR and ECR. Only
approved antennas may be used on the unit’s RF output connectors. These antennas are listed in each
applicable section for each RF type. The use of non-approved antennas may result in a violation of FCC
rules and subject the user to FCC enforcement action. Note that with any installation, there needs to be a
minimum 20 cm spacing between all transmit antennas to avoid co-location difficulties.
Cell Antennas (Aux and Main)—These SMA coaxial connectors are for attachment of cellular antennas.
The MAIN connection is for basic cellular transmission/reception and the AUX connector is for
attachment of a receive-only antenna which provides MIMO receive operation (diversity) with standard
Cell modules, improving signal quality in many installations. In general, both antennas should always be
used for cellular operation. The GE MDS part number for this antenna type is 97-2485A04.
WiFi Antenna—Antenna connection for 2.4 GHz WiFi service. The connector appears similar to the
cellular connectors discussed above, but is a Reverse-SMA type. It contains a pin that matches with an
SMA-F connector. The GE MDS part number for this antenna is 97-4278A34.
To connect an external WiFi antenna, 97-4278A48, a Reverse SMA to N-Female cable and antenna
mount is required. These are not sold from GE MDS but are available from many retailers.
900 MHz ISM Antennas —Antenna connection is a TNC connector. Multiple options are available for
this unlicensed operation.
NOTE For 900MHz ISM operation (NX915 NIC) professional installation is required.
NOTE For Australia and New Zealand the maximum EIRP must be limited to 30 dBm. If ((antenna
gain - feed line loss) + power output setting) > 30), then the power output of the
NX915 must be reduced.
NOTE For regions governed by FCC/IC compliance the maximum EIRP must be limited to 36 dBm. If
((antenna gain - feed line loss) + power output setting) >36), then the power
output of the NX915 must be reduced.

Antenna Type and Orientation (Cell & Wi-Fi)
It is important to use antennas designed to operate in the applicable cellular coverage bands with a Return
Loss of 10 dB or better. Placement of the antennas also plays a key role in the coverage of the system.
While the antennas can be placed directly on the face of the unit in some short range installations, the best
performance is obtained when mounting antennas remotely using low loss coaxial cable. Antennas
mounted in close proximity to each other can couple signals between them and desensitize the RF
module.
When placing the indoor SMA style “paddle” antennas on the face of the unit, position them with a 90
degree angle of separation to improve the isolation. A “V” or an “L” configuration is a common approach
to use with the Main channel typically mounted for vertical polarization. The multipath nature of Cellular
systems means that polarization for indoor use is not normally a critical factor. Isolation between the
antennas is more important.
Indoor use case:
This scenario employs direct mounting of an LTE paddle antenna (GE MDS PN: 97-2485A04) on the
Main and Aux Cell channels and cabled mounting of the Wi-Fi antenna (GE MDS PN: 97-4278A34)
using a magnetic mount (GE MDS PN: 97-4278A78). This configuration offers easy mobility for
evaluation purposes or indoor applications with good cellular signal coverage (see Figure 2-11).
Figure 2-11. Direct Mounting of Cell Antenna; Cabled WiFi Antenna
Minimum 8-inch (20.32 cm) separation between cell and WiFi antennas
This arrangement employs cabled mounting of the LTE paddle antennas (GE MDS 97-2485A04) on the
Main and AUX Cell channels and cabled mounting of the Wi-Fi antenna (GE MDS 97-4278A34) using a
magnetic mount (GE MDS 97-4278A78). The Wi-Fi antenna may also be directly attached to the unit, if
desired. This configuration works well for indoor installations in equipment closets, or for more
permanent applications.
Outdoor use case:
External enclosures—If the system is going to be installed in a weathertight enclosure and mounted
outside in the elements, cabled use of external LTE antennas (GE MDS PN: 97-2485A05) on the Main
and AUX Cell ports, with cabled use of the External Wi-Fi antenna (GE MDS PN: 97-4278A48) is a
good solution. This configuration requires a suitable metallic ground plane for the Cellular antennas (8"
diameter disc minimum for the 97-2485A05 series) or a suitable counterpoise for frequencies as low as
698 MHz Metal enclosures work well for ground plane requirements, when ground contact inside the box
is not impeded by painted surfaces.
Do not use internally mounted antennas inside of metal enclosures.
Other antenna configurations can be easily customized for applications not listed here. Consult your
factory representative for installation matters.
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 33
LN transceivers may be used with a number of different antennas. The exact style and gain factor depend
on regulatory constraints and the physical size/layout of your system. Connection is made to the radio via
a TNC coaxial connector. A directional Yagi (Figure 2-12) or corner reflector antenna is generally used at
remote sites to minimize interference to and from other users. Antennas of this type are available from
several manufacturers, including GE MDS. Contact your sales representative for details.
Figure 2-12. Typical Yagi Antenna (mounted to mast)
Feedlines:
Selection of an antenna feedline is very important. Poor quality cable should be avoided as it will result in
power losses that may reduce the range and reliability of the radio system. The tables which follow show
the approximate losses that will occur when using various lengths and types of coaxial cable. Regardless
of the type used, the cable should be kept as short as possible to minimize signal loss.

3.0 Device Management
This section describes the steps for connecting a PC, logging in and setting unit parameters. The focus
here is on the local serial console interface, but other methods of connection are available and offer
similar capabilities. The key differences are with initial access and appearance of data.
The MCR offers several interfaces to allow device configuration and monitoring of status and
performance. These include local serial console, USB, NETCONF, HTTPS and Secure Shell (SSH) for
local and remote access via the WAN and LAN networks. The serial console, USB and SSH services
offer a command line interface (CLI). There are three user accounts/roles for management access: admin,
tech and oper. User accounts can be centrally managed with a RADIUS server. RADIUS accounts can be
mapped to one of the three user accounts/roles (See “User Management and Access Controls” on Page
176).
NOTE The Orbit MCR device is designed for high security environments. As such, management of the
device does not support Telnet, but instead implements the more secure SSH protocol.
Configuring and managing the Orbit MCR is done by changing configuration data via the Web User
Interface (UI) or from the Command Line Interface (CLI). Either way requires two steps. The first step is
to use a user interface to add, remove, or alter a piece of configuration data. The second step is to use the
user interface to commit the change. Multiple changes can be made prior to committing them. This twostep process allows users to make multiple changes to the configuration and apply them in a bulk commit.
Additionally, the device can validate the bulk commit and reject it if there is an error.
The Device Manager is a built-in software tool that works with your PC’s browser to provide an intuitive,
web-style presentation of all unit information, settings, and diagnostics. Web management uses the unit’s
Ethernet RJ-45 connector
NOTE For security, web access can be enabled/disabled via the CLI using the command: % set
services web http(s) enabled true/false
To connect to the unit and manage it via the Device Manager, you will need the following:
A PC with a web browser program installed.
An Ethernet cable connected between the PC and the MCR as shown in PC Connection for
Web Management.
The unit’s IP address. Check with your Network Administrator, or determine the address via a
command line interface connection. The default address for a factory supplied unit is
192.168.1.1.
The user name and password for the unit. Check with your Network Administrator, or, if a
username and password have not been set, use the factory defaults of admin for both entries.
(For security, a new password should be established as soon as possible after login.)

Connect the unit to a PC via an Ethernet connection. 1.Configure your PC network settings to an IP address on the same subnet as the unit. The default 2.
subnet mask is 255.255.255.0.
NOTE For IP addressing the Orbit MCR uses a routing prefix expressed in CIDR notation instead of
the specifying a subnet mask. The CIDR notation is the first address of a network, followed by
a slash character (/), and ending with the bit-length (max 32) of the prefix. A subnet mask is
expressed in dot-decimal notation. For example, 192.168.1.0/24 is equivalent to specifying
192.168.1.0 with a subnet mask of 255.255.255.0.

There are three tasks that should be performed after initial startup and connection to a PC, as follows:
Create One-Time Programmable passwords for device recovery in the event a password is lost. 1.Change the login passwords. 2.Evaluate the default factory configuration and set it to the user's required security level. 3.
One-Time “Recovery” Passwords 3.1.2
The MDS Orbit platform employs extensive security measures to prevent unauthorized access. As such,
there are no hidden manufacturer passwords or other “back doors” found in less secure products. If a
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 41
password is lost, there is no way to access the unit, except by using a one-time password (OTP) for
recovery. This must be established by the user beforehand. Without a one-time password, the unit will not
be accessible and the hardware will need to be returned to the factory to be re-imaged to defaults.
Technical Support will not be able to assist you if a password is lost, so creating a one-time password is
strongly encouraged. A device with a lost password

One-Time Passwords: How They Work
One-time recovery passwords put control directly and exclusively in the user’s hands. They are similar to
spare keys for a lock. If you make a spare key and put it away safely, you can take it out to quickly gain
entry when your primary key is lost. If you don’t make a spare, you are always at risk of locking yourself
out.
A one-time recovery password is different from the one used to log into the unit on a routine basis. It is
only for use when the primary password is lost or forgotten. When a one-time password is used to log in,
that password is automatically revoked from the list of passwords created. You may create up to five onetime passwords at one time and more can be created if some get used. A password cannot be used again
for log in to the unit, hence the name “one-time” password.
NOTE One-time passwords are only displayed at the time of creation. The password must be saved and
archived at that time. There is no way to view this password again.
Figure 3-7. One-Time Password Add in Setup Wizard
Logging in With a One-Time Password
To use the one-time password for log-in, proceed as follows:
42 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
At the username prompt, enter the word “recovery”. 1.At the password prompt, paste in the one-time-password saved earlier on your PC. Using a one-2.
time-password forces the unit to perform the function which was previously defined when the
password was created:
- factory-reset— The unit resets its entire configuration to factory defaults
- login— The unit allows logging in with admin privileges
Special case: If someone has disabled console access on the COM port, the login prompt will still be
present on that console, but only one-time passwords will be accepted. This is done to provide a way to
recover the unit in the case where the COM1 port has been disabled and the unit cannot be accessed via
TCP (for example; SSH).
Deleting a One-Time Password
As noted earlier, a one-time password is automatically revoked when it is used for log-in. A revoked
password may be replaced, but it must first be removed from the list so a new one can be generated. Any
of the five stored passwords may be removed on demand. As long as there is a free slot, an additional
password can be created, up to the maximum number of five. Logs are generated when the user creates,
deletes or logs in with a one-time-password.
Managing One-Time Passwords
One-Time passwords can be created as part of the Initial Setup Wizard, as shown in the example below.
To view currently configured One-Time Passwords, navigate to
Troubleshooting ---> Status / Recovery Information / Passwords
Figure 3-8. One-Time Password Display Screen
To edit or delete (revoke) a One-Time Password, navigate to:
Troubleshooting ---> Actions / One Time Passwords
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 43
Figure 3-9. One Time Passwords Management Screen
Up to 5 passwords may be added. They may also be deleted. Remember to replace a used password which
is automatically revoked. It must be deleted if there are no more password slots available.
Change Default Passwords 3.1.3
For security purposes it is highly advised to change the default passwords for all user roles. This is
accomplished on the “Change Password” Screen shown below located at:
User Authentication ---> Actions / Change Passwords
Figure 3-10. Change User Password Screen
This feature is also a part of the Initial Setup Wizard, as shown in the Figure below.
44 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
Figure 3-11. User Password Initial Setup Wizard Change Screen
The selected password(s) must follow the rules established on the “Password Options” screen located
under the Basic Config tab of the User Authentication section. These rules may be modified to conform
to the local security requirements.
Security Review 3.1.4
The Orbit MCR provides strong cyber security capabilities that may be customized to meet enterprise
security policy requirements. By default the Orbit MCR is configured with a light level of security. There
are many features and parameters that should be considered and adjusted according to the security policy.
Some of the areas to consider are:
User Authentication 1.
- Update factory default passwords.
- Secure login access into Orbit with local or RADIUS based user authentication.
Device Management 2.
- Secure access to Orbit for device management by enabling/disabling HTTP/HTTPS/SSH.
- It is recommended that HTTP be disabled.
- It is recommended that SNMPv1/v2c be disabled and SNMPv3 be enabled
Static Routing - Limit local broadcast and multicast traffic from being shared with specified 3.
interfaces.
Packet Filtering – Prevent ingress/egress of unwanted traffic by configuring firewall/NAT. 4.Secure end-to-end network links using IPsec VPN with pre-shared-key or certificate based setup. 5.Cellular Security – Utilize IPSec VPN to secure end-to-end cellular link over public cellular 6.

based security setup.
Tamper Detection – Enable tamper detection to detect unauthorized device enclosure removal and 12.
physical movement from authorized install site.
3.2 Preconfigured Settings
The GE MDS factory configuration establishes typical settings based on the types of modules ordered.
The intent is to provide as much out-of-box functionality as possible. For example, in WiFi/Cell
configurations, the unit is configured as a WiFi hotspot.
The Orbit MCR is highly configurable to meet field requirements, but comes preconfigured as
follows:
- The COM and USB ports are enabled for local console operation.
- When applicable, interfaces are preconfigured as members of a bridge.
- A DHCP server is enabled for WiFi clients and the Ethernet LAN ports.
Units are configured with a set of pre-defined defaults set by the factory.
- Default Ethernet IP address 192.168.1.1
- Firewall/NAT/DNS proxy enabled
- DHCP server enabled
Other defaults
WiFi (hotspot):
- Set as Access Point (AP)
- SSID = GEMDS_<SERNUM> SERNUM refers to the unit’s serial number, printed on a
chassis sticker.
- The Ethernet ports are bridged with the WiFi AP.
- SSID broadcast enabled
- Security = WPA2-PSK, CCMP with passphrase: GEMDS_ORBIT
Cellular modem:
- 4G Cellular interface is enabled by default since network can enable connectivity on default
APN.
- 3G Cellular interface is disabled by default since it requires carrier specific APN to be
configured.
ISM Unlicensed 900 MHz radio (NX915):
- Radio Mode set to Remote
- Modem Mode 500kbps
- Power at 30 dBm

Differences between Serial and SSH 3.4.1
Serial and SSH both present identical management capabilities, but the method of access is different for
each. Serial involves an RS-232 serial connection from a PC to the unit’s COM port. SSH uses an
Ethernet PC connection to the unit’s ETH port. Maximum recommended cable length for a serial
connection is 50 feet (15 meters). SSH can be connected to the unit from any network point that has
connectivity with the PC, including remotely over the Internet, or using other networks.
The focus of these instructions is on Serial access, but SSH may also be used by following these
additional points, which replace Steps 1-3 below:
Connect to the unit with a PC that is in the same IP network as the MCR. Launch an SSH client
program and connect to the unit using its programmed IP address.
The default IP address for the unit is 192.168.1.1. If you do not know the current IP address of the
unit, follow the serial configuration instructions below, where you can determine the address and
continue configuration, or check with your network administrator.
Establishing Communication—Serial Interface 3.4.2
Follow these steps to configure the unit for its first use with serial console interface:
Connect a PC to the unit’s COM port as shown in Figure 3-16. Maximum recommended cable 1.
length is 50 ft/15 m.
NOTE Not all PCs include a serial port. If one is not available, the Orbit MCR’s USB port can be used
to access the device management console by using a Mini-USB cable between the device and a
PC. The PC needs to install the device driver.
NOTE If the COM port has been configured for terminal server operation, pressing +++ switches it to
console (management) mode. Serial console mode is required for the following steps.
Launch a terminal communications program, such as HyperTerminal, with the following
communication parameters: 115200 bps (default speed), 8 bits, no parity, one stop bit (8N1) and
flow control disabled. Incorrect parameter settings are a frequent cause of connection difficulties.
Double check to be sure they are correct.
An adapter may be used to convert the unit’s RJ-45 serial jack to a DB-9F type (GE MDS part no.
73-2434A25). If no serial port exist on the PC, a Mini-USB cable may be connected between the
MCR’s USB device port and the PC.

The following sections describe key operational features of the MCR unit and list configuration options
for them. Each major heading begins at the top of a new page. For this reason, large areas of white space
exist at the end of some sections. This is done to provide a clear delineation between major sections.
NOTE The LAN port should be assigned IP addresses only if it is a routed interface (that is, not in a
bridge).
NOTE The commands that follow in this section vary depending on the Orbit MCR options ordered.
3.5 Interface Configuration
Serial Interface 3.5.1
Understanding
Orbit supports COM ports (RJ45) that can be used for either console access (the CLI) or payload data.
Depending on ordered options, the unit may have multiple COM ports. COM ports serves as the primary
interface for connecting the unit to an external DTE serial device supporting RS-232 or RS-485. By
default, a COM ports are enabled for local console control, using 115200 bps with 8N1 format.
A mini-USB-to-USB cable may also be used to connect to a Computer in case no physical serial device
exists. If a mini-USB connection is used, the computer must contain the appropriate device driver. A
driver for serial operation can be found on GE MDS website.
Orbit considers the COM ports and the USB as members of a broader interface category called “serial
ports”. In Orbit, serial ports include any user addressable interfaces that pass serial bytes. Depending on
configuration, serial ports may also include virtual ports that provide access to the serial data stream of
internal Orbit interfaces. This is useful, for example, to allow the Orbit to access the over-the-air serial
data stream of legacy licensed narrowband MDS radios.
Serial ports in Orbit can be used in one of three ways:
Console / Command Line access – the CLI for administering the unit 1.Terminal Server – conversion between serial and IP 2.Serial Pass-Through – direct connection between serial interfaces 3.
Configuring
The screens below shows examples for how to configure the COM1 and USB serial ports:
Navigate to: Serial ---> Basic Config / Ports

Click on the USB1 to get:
NOTE For serial ports other than physical COM ports, the only useful attributes are Vmin and Vtime.
Other settings like line mode, baud rate, and flow control are ignored.
Vmin - Receive Buffer Size - The minimum number of data bytes that will be buffered by the serial
port before handling of the data to be processed by the terminal server. (255 = DEFAULT).
Vtime - Receive Inter-Byte Timeout - The amount of time between bytes of data on the serial port in
milliseconds that indicates the end of a serial message ready to be processed by the terminal server.
(100 = DEFAULT)
Console Settings
Any physical serial port can be set up as a console port by adding the port under the Console tab.
Navigate to: Serial ---> Basic Config / Console
From the CLI, this sequence shows how to add console access to the COM1 and COM2 serial ports and
set the COM2 baud rate to 19200 bps:

% set services serial ports COM2 baud-rate b19200
% commit
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 63
Terminal Server Settings
When configuring a serial port that will be used as a terminal server the VMIN and VTIME settings need
additional explanation. As described above VMIN is a number describing bytes that are received from the
interface, while VTIME is a delay value in milliseconds. These parameters act together to control serial
data collection and transmission as described below:
VMIN == 0; VTIME == 0: The terminal server will continuously read to see if a byte if data is
available and process each byte.
NOTE While this is a valid mode in most cases this causes a high processing load on the device that
may impact performance of other operations of the device.
VMIN > 0; VTIME == 0: The terminal server waits to process data until at least VMIN bytes
of serial data are received.
VMIN == 0; VTIME > 0: If serial data is received, the terminal server will continuously read
the number of bytes available until VTIME has elapsed then process the data.
VMIN > 0; VTIME > 0: Once an initial byte of input becomes available the terminal server
waits until the MIN bytes have been read, or when the inter-byte timeout expires. The timer is
restarted after each further byte is received and because the timer is started only after the initial
byte is received, at least one byte will be read.
For more information on Terminal Server configuration see 3.8.14.
Pass-Through Settings
Orbit offers Serial Pass-Through operation as a low-overhead means to transport serial data. Unlike
Terminal Server operation, there is no need to convert the serial data to IP.
A Pass-Through Instance defines the connection between the two serial ports.
Navigate to: Serial ---> Basic Config / Pass-Through
64 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
The example below defines a Pass-Through Instance to connect COM1 to an Orbit LN operating in
transparent-serial mode (backward compatible to x710). First the instance is named as shown:
Next the connection is specified between the ports, labeled Port 1 and Port 2.
Clicking the “…” button provides the serial port choices. In this example, COM1 is the physical serial
port; LnRadio-serial is the virtual serial port created automatically when an Orbit LN interface is
configured for “transparent-serial” operation.
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 65
The last image below shows the final configuration prior to selecting the “Finish” button.
Note that the“Display Banner” check-box at the bottom applies to ports that also function as Console
ports. It indicates whether or not an informational message is displayed on startup describing that the port
is going into data mode and not available for console use.
Serial Hardware Flow Control
Hardware Flow Control: When operating in CTSKEY mode, all serial ports in the data path are required
to be set to the same baud rate, and that VMIN and VTIME remain at the defaults for serial data packets
less than or equal to 255 bytes. For serial packets over 255 bytes it is recommended that a cts-delay time
of at least 90ms be used to account for the VTIME delay of the over-the-air sending unit.
Hardware Flow Control Modes:
DCE1.
CTS follows RTS after a programmable CTS delay.
If the unit’s input buffer approaches a full condition it can deassert CTS regardless of state of
RTS.
CTSKEY 2.
Based on legacy MDS devices including TransNET and SD, the device will act similar to a
DTE but will provide signaling on the CTS line instead of the RTS line.
When the first character of a transmission is ready to be sent to the serial port, the unit shall
assert CTS and delay for CTS delay time expiration before outputting the first character.
After the last character of a transmission is output from the serial port, the unit shall keep CTS
asserted until the expiration of CTS hold time.
CTSKEYPLUS 3.
The unit shall support flow control (Throttling) on the RTS pin. The device is expected to be
wired via null modem to an external DCE device. The CTS line of the external DCE device
drives the RTS line of the unit.

Orbit MCR supports routing of TCP/UDP/IP data from the Cellular WAN network interface to any of the
other network interfaces (including WiFi or LAN) using the IPsec VPN or network address and port
translation (NAPT) feature and to the COM1 (or COM2) serial port using the terminal server service. The
configuration of these use cases is specified in the respective sections on VPN, Firewall and NAT and
Terminal Service.
The cellular modem inside the unit supports main (primary) and secondary antenna (for receive diversity).
The primary antenna must be installed for the cell modem to register with the cellular network. It is
strongly recommended that a secondary antenna be installed for achieving a robust cellular link. There
should be no physical obstructions around the antennas. The main and diversity antennas must have at
least 27 dB of isolation from each other to ensure optimal operation of the cellular modem. For Antenna
Installation assistance, see “Antenna Planning and Installation” on Page 31 or contact your local GE MDS
representative. See the below table for approved Antenna Types.
Table 3-4. Approved Cell Antenna Types
Table 3-5 describes the Orbit MCR’s LED behavior when using the cellular interface.
Table 3-5. Cell Interface LED Descriptions
SIM Port(s) - These ports accept a mini SIM card (2FF type) for cell operation. The unit’s cellular
interface will not function without a valid SIM card installed. Users are responsible for obtaining a
provisioned SIM card for the appropriate service plan from their cellular provider. Information on
determining the cell module’s IMSI/IMEI (typically required for provisioning) is provided on Page 79 of
this manual.
CAUTION: Do not insert the SIM card when the unit is powered on.
Card Insertion: The SIM card only inserts one way; do not force it. It should be inserted with the printed
label facing up and the cut-off corner on the left side (see figure below). A small instrument, such as a
flathead screwdriver, may be helpful to gently push the SIM all the way in until it locks.
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 69
Figure 3-22. Steps for Inserting the SIM Card
NOTE The insertion example above shows the default SIM slot (Slot A). Units equipped with multiple
SIM ports will label the upper slot SIM B and the lower slot SIM A.
NOTE Dual SIM functionality is a selective order-entry feature. Default units are shipped with only
SIM-A enabled; SIM-B is not supported.
Configuring
A Connection Profile must be configured for the unit to establish a data connection with the cellular
network. A connection profile allows the user to configure various parameters related to the cellular
connection. One or more connection profiles can be configured on the unit. The order of the connection
profiles can be chosen by the user. The unit will use the first connection profile to establish connection
with the cellular network. If connection profile switching (described later) is enabled, then the unit will
switch to second profile in the list if it is unable to establish a connection using the first profile after a
configurable, specified timeout.
An Orbit MCR equipped with a Verizon 4G LTE modem is shipped out of the factory with the cellular
interface enabled and a connection profile (named PROFILE-1) configured to connect with Verizon's
Internet Packet Data Network (PDN).
An Orbit MCR equipped with a 3G GSM modem is shipped out of the factory with the cellular interface
disabled. The user will need to create a connection profile with the cellular network specific parameters
prior to enabling the interface to allow unit to connect to the network.
In the UI, start on the following page: Interfaces / Cell ---> Basic Config / Cellular
Figure 3-23. Connection and Connection Profile Switching UI Screen
70 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
The cellular configuration is configured by creating a “Connection Profile” to describe the connection and
consists of four major groups of information:
Network Configuration - contains various parameters related to how the modem registers with the
cellular network.
Bearer Configuration - parameters related to data connection with the cellular network.
Keep Alive - Keep alive configuration for sending ICMP Echo messages to a remote host/server
periodically to keep the connection alive
Service Recovery - Service recovery configuration
If multiple cellular providers are supported, the “Connection Profile Switching” choices may need to be
configured.
The following is an example UI screen to create a connection profile named ORBIT1 by clicking on the
ADD button and naming the profile as such.
Figure 3-24. Example Connection Profile
Each Connection Profile has grouped information that contains specific information to be selected. The
choices are described below:
Network Configuration - contains various parameters related to how the modem registers with
the cellular network.
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 71
Technology-selection - The user can configure the modem to automatically select the network
technology to connect to (automatic) or force it to register only on:
- Automatic (DEFAULT)
- 2G GSM (geran),
- 3G UMTS (utran),
- 4G LTE (e-utran),
- 2G CDMA(cdma-1xrtt)
- 3G CDMA EV-DO (cdma-evdo).
Service Domain - Network Service Domain - choices are:
- Circuit Switched (CS) and Packet Switched (PS)
- Packet Switched (PS) Only
If cellular network does not support CS then configure as PS Only. Consult your service provider for this
information. Typically, this field is left as default.
Bearer Configuration - parameters related to data connection with the cellular network.
Apn - Once the unit has registered to the cellular network, it sets up the IP data connection
with a specific Packet Data Network (PDN) identified by the Access Point Name (APN). APN
is a string identifier. An Orbit MCR equipped with a Verizon 4G LTE modem comes
preconfigured with an APN of vzwinternet. Hence, it attempts to set up a data connection
towards Verizon's internet PDN that provides internet connectivity. For this data connection to
succeed, a SIM card that has been provisioned for internet access needs to be obtained from
the Verizon Wireless and installed in the unit. See “ APPENDIX E – Obtaining Provisioned
4G/LTE Service (Verizon)” on Page 429. If a private network (PN) account has been set up
with Verizon wireless, a SIM card will be issued from that account. When the modem is
powered up with such a SIM, the default APN on the modem is automatically updated to the
one that identifies the user’s private network. This procedure is called OTA APN update. This
procedure might not always succeed and hence, may require the user to manually update the
APN on the MCR.
The following example shows how to update the APN to, MYAPN.GW6.VZWENTP, manually,
via the CLI:
% set interfaces interface Cell cell-config connection-profile PROFILE-1 bearer-config
apn MYAPN.GW6.VZWENTP
% commit
An Orbit MCR equipped with a 3G GSM modem is shipped out of factory with cellular
interface disabled. The following example shows how to create a connection profile to allow it
to connect to, for example, AT&T's 3G GSM network with an APN entitled "Broadband":
% set interfaces interface Cell cell-config connection-profile AT&T bearer-config apn
Broadband
% set interfaces interface Cell enable true
% commit
Protocol - This parameter specifies the Packet Data Protocol (PDP) type. DEFAULT - “IP”.
NOTE The user should leave this parameter to the default value of IPv4 - IPv6 functionality is not
currently supported.
Auth-type, Username, Password - These parameters should be set if the cellular network
provider requires a username and a password along with authentication protocol (PAP, CHAP
or PAP/CHAP) to be specified. The user does not need to configure the MCR with 4G LTE
modem with these parameters. The user may need to configure MCR with 3G GSM modem
parameters, depending on the cellular network.
72 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
Mtu - Maximum Transmission Unit in bytes - leave at the default value of 1500, unless
directed by technical support to change.
Request DNS – If enabled, the DNS servers used by the system are obtained by the DHCP
client running on this interface.
Request Routers - If enabled, default route used by the system is obtained by the DHCP
client running on this interface.
NOTE If multiple interfaces are configured to obtain addresses using DHCP, only, one of the
interfaces should enable request-dns and request-routers parameters.
Keep Alive - The keep-alive feature allows the cellular modem to maintain connection in situations
where no traffic is passed over the cellular link for long periods of time or when the traffic is
traversing through a NAT middle box in the network and where the mobile terminated traffic can be
sent only if the NAT entries exist for corresponding mobile originated traffic. The keep-alive
mechanism sends an ICMP echo message to the configured address/name at the configured interval.
This feature should be used only if an application is passing data very infrequently over a cellular
connection (i.e., if data is passed at a rate of less than once per hour).
Address - This parameter specifies the address or DNS name of the destination host to which
keep-alive messages should be sent
Interval - This parameter specifies the time interval (in minutes) between keep-alive messages
Recovery on Timeout - This parameter enables the connectivity recovery mechanism to reset
the cellular modem if no response to the keep-alive messages are received up to max-numretries attempts. DEFAULT - true if the keep-alive feature is configured
Max Num Retries - This parameter specifies the number of keep-alive messages that are sent
before modem recovery is attempted. DEFAULT - 15 - configurable only when recovery-ontimeout is enabled.
Service Recovery - The service recovery configuration block contains various parameters related to
service recovery feature. The service recovery mechanism is meant as a watchdog mechanism for the
cellular connection, where the cellular modem is reset by the following conditions:
- The unit is unable to register at all on the network.
- The unit is unable to register specifically to the LTE service.
General Recovery Interval - This parameter specifies the time interval after which the
cellular modem is reset if the modem-state does not transition out of the 'unknown' state.
DEFAULT - 300sec (5 min).
Lte Recovery – For an Orbit MCR equipped with an LTE modem, this parameter enables
LTE service recovery. The LTE service recovery mechanism resets the cellular modem if it is
stuck in 3G service-state (EV-DO or UMTS) for more than the lte-recovery-interval. This is
enabled by default. This parameter affects only units with LTE capable modem.
Lte Recovery Interval - For an Orbit MCR with an LTE modem, this parameter specifies the
time interval (in sec) after which, the cellular modem is reset if the modem-state does not
transition to 'LTE' service-state. DEFAULT - 900 sec (15 min).
% set interfaces interface Cell cell-config service-recovery lte-recovery false
% commit
NOTE The Lte Recovery mechanism should be disabled if the unit is deployed in areas that either lack
or have poor LTE coverage. Otherwise, the cellular modem and hence the cellular data
connection will be unnecessarily reset every 'lte-recovery-interval' seconds.
sim-slot - This parameter specifies the SIM slot that should be used to read the SIM card.
Orbit MCR units equipped with cell may have one or two SIM slots: SIM-A and SIM-B.
DEFAULT - SIM-A. The slots are located on the outside of the case, on the front panel. If
MDS 05-6632A01, Rev. G MDS Orbit MCR/ECR Technical Manual 73
multiple slots are provided, the upper slot will be labeled SIM-B and the lower slot will be
labeled SIM-A.
NOTE The sim-slot option will not be visible unless Dual SIM functionality is installed in the factory
as part of the selective order-entry feature, for the 3G module. By default units are shipped with
only SIM-A enabled; SIM-B is not supported.
In addition to the Connection Profile configuration, the Connection Profile Switching feature allows a
user to enable switching when one or more profiles are configured on a unit. This feature can be used to
implement dual SIM functionality, where the user obtains and configures a unit with two SIM cards, each
from a different cellular provider. This can help increase the reliability of the connection by allowing the
unit to switch to a different SIM card if data connection with the other SIM card fails for any reason (for
example, due to reduced signal strength and so on).
For example, the UI screen for a Connection Profile Switching is shown below:
Interfaces / Cell ---> Basic Config / Cellular
Figure 3-25. Connection Profile Switching Example
Switch to Next on Roaming - This parameter enables connection profile switching when the
roaming-state of current connection changes to roaming. DEFAULT - FALSE (disabled).
Switch to Next on Failure - This parameter enables connection profile switching when data
connection failure occurs when using the current profile. DEFAULT - FALSE (disabled).
Switch to Next on Failure Timeout - This parameter specifies the time interval for which
data connection is attempted using the current connection profile before switching to next one
in the list. DEFAULT - 30 min.
Switch to First on Timeout - This parameter enables switching of connection profile to the
first one in the list irrespective of current connection status. DEFAULT - FALSE (disabled).
Switch to First Timeout - This parameter specifies the time interval after which data
connection is attempted using the first profile in the list regardless of current connection status.
DEFAULT - 60 min.
NOTE The cellular provider network can disconnect the cellular connection if any packets get routed
from LAN to Cellular interface without undergoing masquerading (Source Network Address
Translation (NAT) before exiting the cellular interface. Therefore, always configure
masquerading on the cellular interface. See “Source NAT (Masquerading)” on Page 236 for
more information on NAT configuration.
Use of the “Connection Profile Switching” feature requires the user to configure two profiles; each with
specific cellular provider information for the respective SIM slot. For example, say the SIM card from
carrier A is inserted in SIM-A and the SIM card from carrier B is inserted in SIM-B.
Configure a profile for carrier A to use SIM-A:
% set interfaces interface Cell cell-config connection-profile CARRIER_A bearer-config apn
carrierA.apn
% set interfaces interface Cell cell-config connection-profile CARRIER_A sim-slot SIM-A
Configure a profile for carrier B to use SIM-B:
74 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
% set interfaces interface Cell cell-config connection-profile CARRIER_B bearer-config apn
carrierB.apn
% set interfaces interface Cell cell-config connection-profile CARRIER_B sim-slot SIM-B
Enable connection profile switching on connection failure
% set interfaces interface Cell cell-config switch-to-next-on-failure true
Enable cell and commit configuration
% set interfaces interface Cell enable true
% commit
NOTE Dual SIM functionality is a selective order-entry feature. Default units are shipped with only
SIM-A enabled; SIM-B is not supported.

Understanding
The Orbit MCR device may be configured to have an internal WiFi module that has FCC/CE modular
approval. The WiFi module can be configured to operate as an 802.11b/g/n Access Point or Station. The
specifications for the WiFi module are covered in “2.4 GHz WiFi Specifications” on Page 395. The table
below contains the list of GE MDS approved antennas.
Table 3-6. Approved Cell Antenna Types
The unit supports the following WiFi security modes:
None (should be used only to test connectivity) 1.WPA2 + CCMP/AES Encryption – This mode should be used if all client devices support 2.
WPA2/CCMP.
CCMP/AES Encryption + TKIP Encryption – This mode should be used if there is mix of both 3.
legacy client devices that only support WPA/TKIP and newer devices that support WPA2/CCMP.
In this mode, stations must select only TKIP or AES/CCMP + TKIP. Stations cannot specify only
AES/CCMP. Table 3-7 shows the valid combinations of Station Encryption settings that will work for a
given AP Encryption setting.

Enterprise – This supports EAP-TLS based authentication of client devices (configured with
certificates/keys) via RADIUS.
The default SSID is based on the unit’s serial number and takes the form of: GEMDS_<SERNUM> (the
serial number is printed on the chassis sticker). The default password for WiFi operation is
GEMDS_ORBIT.
The table below describes the Orbit MCR’s LED behavior when using the WiFi interface. The LED for
the NIC varies, depending on the configuration of the MCR. When equipped with 900 MHz support,
WiFi information is in NIC 1; otherwise, it is in NIC 2.

The CLI commands below show how the WiFi settings are made. The unit must be in Configuration
Mode to make these settings. Each command string begins with the word set:
% set interfaces interface Wi-Fi wifi-config mode access-point ap-config ap GEMDS_<SERNUM>
The Orbit MCR supports up to two SSIDs to be configured when the Wi-Fi interface is set to an Access
Point. The first SSID should be reserved for high throughput data paths. The second SSID is intended to
support auxiliary applications such as a dedicated management connection or guest LAN access. The
following example demonstrates having a second Wi-Fi AP with the SSID:
86 MDS Orbit MCR/ECR Technical Manual MDS 05-6632A01, Rev. G
Figure 3-34. WiFi AP Configuration
To set up a second WiFi access point with the CLI, use the following command by substituting the
different SSID and PSK for the new configuration.
The channel, operation mode, tx-power, dtim-period, rts-threshold and fragm-threshold
parameters are shared between the two SSIDs.
The Orbit MCR organizes the SSIDs in alphabetical order. If an SSID of ssidexample exists
and a second SSID of examplessid is created, this will become the first SSID and the SSID
ssidexample will become the second SSID.
Each SSID is independent of the other, except for the parameters noted above. Each SSID can
be in or out of the bridge. However, to use VLANs, the SSIDs must be bridged.

alarm is generated by the unit to indicate a VSWR Error condition. This must be corrected in order for the radio to
operate properly and to ensure optimal operation.
NOTE The only required steps for basic configuration are programing a network name in all units and
establishing one unit as the AP.
Minimal configuration is necessary but several advanced tuning facilities are provided.
Frequency operating range is restricted by pre-set factory calibration to ensure compliance with
applicable country-specific regulatory requirements. Frequency operating range can be further restricted
by user input to avoid select portions of the operating band. This is sometimes helpful when attempting to
collocate a network with another 900MHz network, such as the MDS iNET or TransNET. For example
the iNET network can be configured to operate in the top half of the band while the Orbit can have its
NX915 module configured for the lower half.
By default the radio ships from the factory with the 500kbps modem selected. Dwell time is set to 50ms
and Hop Set A is enabled. For typical configuration (e.g., North America) this provides 27 discrete
channels over which to hop.
Hop Sets provide a way of specifying the minimum channel spacing within the band and implicitly define
the maximum number of hops. Hop Set A uses 307.5 kHz spacing and provides 80 channels. (Required
for Modem selections 125kbps and 250kbps).
Table 3-11. Selected Modem Modes
See “APPENDIX F – NX915 Module Frequencies” on Page 430 for a chart listing RF
channels/frequencies in each hop set, as they apply to each modem selection.
Other items of interest for tuning configuration include Modem Mode (125kbps, 250kbps, 500kbps, etc.)
and dwell time. For remotes, setting modem mode to “auto” allows remotes to automatically follow the
configuration of the AP. Setting the remote to use a specific modem trades faster sync times for system
flexibility. Dwell time determines how frequently the radio switches channels. Longer dwell times are
more efficient for data transport and provide higher throughput; but smaller dwell times provide faster
synchronization and are more robust in weak signal environments or in the presence of interferers.

For the advanced user, the module supports configuring more items including:
Data Retries - Number of times to retry unicast data before declaring NACK.
Fragment Threshold - Fragmentation threshold
Lna State - Controls the low noise amplifier
Mcast Repeat - Number of times to repeat downstream broadcast and multicast data.
Propagation Delay - Correction for the propagation delay of the RF signal.
Stale Packet Timeout - If the MAC is unable to transmit a packet in this time, it will drop the packet.
In general, it is recommended that users start with the simplest configuration and then make parameter
changes as necessary to meet specific needs.
NOTE Frequency blocking to meet country specific regulatory requirements may be configured for by
the factory to disallow operation. These settings can NOT be changed or modified by the user.

Important Notes and Information Regarding LQI
LQI is dependent on the modulation format and should be used as a relative measurement of the link
quality. A low LQI value indicates a better link quality than a high value. Algorithmically, using GFSK
modulation, the transceiver calculates the value by measuring the frequency of each "bit" and compares it
with the expected frequency based on the channel frequency and the deviation and the measured
frequency offset.
- LQI is a metric of the quality of the received signal. It is a dynamic value that is computed only
when data is received on the RF interface, and should be refreshed accordingly.
- Unlike RSSI which simply measures signal strength, LQI is only a measurement of the
"correctness" of this signal. (This means how easily the received signal can be correctly
demodulated.)
- In general the lower the LQI the better the quality.
- LQI should be used as a "relative" measurement. Precision is fairly loose and subject to
variation from radio to radio and modulation format.
