QJET cross connections
Expand the E1 / T1 display by clicking on the relevant icons.
The QJET card can operate in several modes allowing you greater flexibility in tailoring or grooming
traffic. The Data type selection are Off, E1, or T1 rates.
Note: An unframed E1 / T1 port requires 5 bits (or 40 kbit/s) of overhead traffic per port for
synchronization.
An unframed E1 port with 2048 kbit/s of traffic requires 2088 kbit/s of link capacity.
An unframed T1 port with 1544 kbit/s of traffic requires 1584 kbit/s of link capacity.

E1 Framed Modes
Framed Mode Description
E1 – PCM 30 Provides 30 timeslots to transport traffic. Timeslot 16 carries channel
associated signalling data (CAS).
E1 – PCM 31 Provides 31 timeslots to transport traffic. Timeslot 16 can be used for common
channel signalling or to transport traffic.
E1 – PCM 30C Same as E1 – PCM 30 mode but supports CRC-4.
E1 – PCM 31C Same as E1 – PCM 31 mode but supports CRC-4.
E1 CRC-4 (cyclic redundancy check) is used to ensure correct frame alignment and also used to
gather E1 performance statistics e.g. Errored Seconds (ES), Severely Errored Seconds (SES).
The first three bits of timeslot 0 NFAS (bits 0,1 & 2) and all of timeslot 0 FAS are not transported
across the link, but rather terminated and regenerated at each terminal.
The last five bits of timeslot 0 NFAS (bits 3 – 7) are the National Use Bits (NUBs) which can be cross
connected locally or over the link.
E1 - PCM 30 mode
E1 - PCM 30 modes are used when access to the signalling bits (ABCD) is required, for example:
Splitting a PCM 30 E1 into two separate PCM 30 E1s
Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into an PCM 30 E1
Drop and Insert connections between PCM 30 E1s
In PCM 30 / PCM 30C mode, the timeslot table left column is used to map timeslot bits and the
timeslot table right column is used to map CAS bits (ABCD) for signalling. Timeslot 16 is reserved to
transport the CAS multi frame.
One use of this mode is to connect the 4 wire E&M interfaces to third-party multiplexer equipment over
the E1 interface using CAS in TS16 to transport the E&M signalling.
To configure this mode correctly, you must have a detailed knowledge of the CAS signalling modes for
the third-party equipment to ensure the signalling bits are compatible and configured to interoperate.
E1 - PCM 31 mode
E1 - PCM 31 modes are used to cross connect timeslots bits without the signalling bits (ABCD).
TS16 can be cross connected between E1 ports (to transport the entire CAS multi frame) or used for
common channel signalling or to transport traffic.
The timeslot table left column is used to map timeslot bits but the timeslot table right column for CAS
bits (ABCD) is not used.

T1 - SF 4 mode
T1 SF 4 mode provides 24 timeslots to transport traffic using the G.704 12 frame Super Frame with
four state demultiplexed signalling using the AB bits.
The mapping left column is used to map timeslot bits and the timeslot table right column is used to
map the CAS A&B bits for signalling (C&D bits are not used).
T1 SF mode is used when access to the signalling bits is required, for example:
Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into a 12 frame Super
Framed T1 using ‘multiplexed’ signalling from the interface.
Drop and Insert connections between 12 frame Super Framed T1s or data interfaces
T1 - ESF mode

Symmetrical Connection Wizard
The Cross Connections application has a Symmetrical Connection Wizard which simplifies the cross
connection configuration when the terminals are fitted with symmetrical / matching interface types.
A symmetrical connection is a connection between the local and the remote terminal where the local
slot, card type, port and connection details are identical to those of the remote terminal.
The only exception is DFXO / DFXS connections where DFXO cards are considered to match DFXS
cards (as they normally interwork).
Framed E1 / T1 CAS connections, drop-and-insert connections, and connections that do not involve
entire timeslots, are considered to be asymmetrical.
Starting the wizard
When starting the wizard with unsaved changes, the following popup dialog should appear
Click on 'Save' if you wish to save the current configuration to a file. Clicking on 'Continue' will continue
with the wizard and overwrite any changes made when the wizard finishes.
The wizard can be cancelled at any time by clicking on the 'Cancel' button or by closing the window.
Wizard Navigation
Click on the Next button to progress through the wizard. The current stage is indicated in the
navigation bar on the left. You can jump directly to a stage by clicking on the stage required.

11. Protected terminals
Monitored Hot Stand By (MHSB)
This section describes configuring the protected terminal in MHSB mode. A protected terminal in
MHSB mode comprises two radios interconnected using the tributary and RF switches as shown
below:
The MHSB switch protects terminals against any single failure in one radio. It also monitors the alarm
output of each radio and switches between radios if major radio link alarms occur.
The MHSB switch uses a CPU to monitor the alarm status received from both the connected radios'
alarm ports. When a relevant major radio link alarm is detected on the active radio (that is, transmitter,
receiver, power supply or modem), the CPU switches a bank of relays that switches all the interfaces
and the transmit port from the main radio to a functioning stand-by radio. The stand-by radio now
becomes the active radio.
The tributary switch and the RF switch are both a 19-inch rack-mount 1U high chassis. The total rack
space required is 6U. The MHSB switch option is available for the following bands: 300, 400, 700, 900,
1400, 2000, and 2500 MHz.

Slave tributary switches
Each tributary switch protects up to eight ports. Up to three slave tributary switches may be added to a
MHSB terminal to protect up to 32 ports. Each slave tributary switch is interconnected by means of the
slave tributary switch ports on the RF switch, as shown below.
Note: A tributary switch that is operating as a slave (rather than a master) has a RJ-45 V.24 loopback
connector plugged into the console port. If the connector is missing, contact Customer Support.
Alternatively, you can make this connector. Follow the standard pinouts for a V.24 RJ-45 connection
(see "
QV24 Interface connections" on page 228).
Protected terminals | 157
MHSB cabling
The two radios are interconnected as follows:
Caution: Do not connect Transmit to Receive or Receive to Transmit as this may damage the radio or
the MHSB switch.
Cables supplied with MHSB
The following cables are supplied with a MHSB terminal:
Ethernet interface: RJ-45 ports standard TIA-568A patch cables .
Alarm interface: RJ-45 ports standard TIA-568A patch cables.
RF ports: two QMA male patch cables are supplied.
MHSB power supply
See “DC power supply” on page 32 and “AC power supply” on page 35.
Protected terminals | 158
Configuring the radios for protected mode
The MHSB switch does not require any special software. However, the radios connected to the MHSB
switch must be configured to work with the MHSB switch. This sets the alarm outputs and inputs to
function in MHSB mode.
You must configure the interfaces of both radios connected to the MHSB switch identically. To perform
this, you can either connect directly to the radio or use the test mode of the MHSB switch.
IP address setup
Before configuring the link, you must ensure that the two independent links have correctly configured
IP address details.
All four radios in the protected link must be on the same subnet.
Protected terminals | 159
Mounting the MHSB radios and switch
Once the IP addresses are correctly configured, it is important to connect the A and B radios' Ethernet
and Alarm ports correctly. In general, mount radio A above the MHSB switch and radio B below the
MHSB switch:
There is an Ethernet connection between any of the four Ethernet ports on each radio and the
Ethernet port on the Tributary switch. There is also a connection between radio A and radio B, which
ensures Ethernet traffic is maintained if a radio loses power.
The Ethernet port on the protection switch can be connected to an Ethernet hub or switch to allow
multiple connections.
Important: The management Ethernet capacity on each of the four radios in the protected terminal
must be identical for remote communications to work and there should only be one IP connection to
the management network (via the tributary switch Ethernet port).
Protected terminals | 160
Configuring the terminals for MHSB
It is recommended that you configure the local and remote A side first, then the local and remote B
side. Both the local A and B radios must be configured identically, and both the remote A and B radios
must be configured identically.
Tip: As illustrated below, you may find it helpful to have two browser sessions running simultaneously.
You can then easily see both the A and B sides of the protected link.
To configure MHSB operation:
1. Select Link > Maintenance > MHSB.
2. Enable MHSB mode.
3. Select whether the radio is A or B.
Ensure that the radio connected to the A side of the protection switch (normally above the MHSB
switch) is set to Radio A and the radio connected to the B side of the protection switch (normally
below the MHSB switch) is set to Radio B.
In the event of a power outage, the radios will switch over to the A side of the protection switch
when the power is restored. The A side is also the default active side.
4. When you have made your changes, click Apply to apply changes or Reset to restore the previous
configuration.
5. Repeat steps 2 to 4 for the other side of the protected link.
Protected terminals | 161
Clearing MHSB alarms
If a switchover event occurs, the OK LED on the front panel and on the Terminal status and menu bar
in SuperVisor changes to orange.
1. Select Clear Switched Alarm from the MHSB Command drop-down list.
2. Click Apply to apply changes or Reset to reset the page.
Note: When MHSB mode is enabled, external alarm input 2 is used by the protection system to carry
alarms from the protection switch to the radio. In MHSB mode, therefore, only external alarm input 1 is
available for user alarms.
In-service commissioning | 163
12. In-service commissioning
Before you start
When you have finished installing the hardware, RF and the traffic interface cabling, the system is
ready to be commissioned. Commissioning the terminal is a simple process and consists of:
1. Powering up the terminals
2. Configuring both the local and remote terminals using SuperVisor
3. Aligning the antennas
4. Synchronizing the terminals
5. Testing the link is operating correctly. As a minimum, conduct the suggested tests to ensure
correct operation. More extensive testing may be required to satisfy the end client or regulatory
body requirements.
6. Connecting up the client or user interfaces
What you will need
Appropriately qualified commissioning staff at both ends of the link.
Safety equipment appropriate for the antenna location at both ends of the link.
Communication equipment, that is, mobile phones or two-way radios.
SuperVisor software running on an appropriate laptop, computer, or workstation at one end of the
link.
Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters.
Predicted receiver input levels and fade margin figures from the radio link budget (You can use
Surveyor (see "
Path planning" on page 19) to calculate the RSSI, fade margin, and availability).
