1Introduction
This document describes how to connect a QuadroE1/T1 to a Quadro16x and configure both
devices so that the QuadroE1/T1 can be used as a PSTN trunk extension for the Quadro16x. This
will allow the users of the Quadro16x to have up to 30 emulated PSTN lines.
The QuadroE1/T1 is a VoIP gateway that allows connectivity between the PSTN and a VoIP network
via its E1/T1 lines using CAS/CCS signaling. E1, the European system, allows 30 active timeslots
both for CAS and CCS. T1, the United States system, allows 24 timeslots if CAS is used and 23 if
CSS is used.
This document describes only the configuration procedures required for the described scenario. For
more information on the setup of the Quadro16x or the QuadroE1/T1, please refer to
Administrator’s Guide for the corresponding device found in the Downloads section of Epygi’s
Technical Support Center (www.epygi.com).

4Preparations
Before integrating the QuadroE1/T1 into the LAN of the Quadro16x, both devices must be
appropriately pre-configured. The required steps are detailed below.
4.1 Preconfiguration of Quadro16x
1. Ensure that the Quadro16x acts as a DHCP server on its LAN. (see 4.1.1)
2. Obtain an IP address from the DHCP IP address range of the Quadro16x. This address will be
assigned to the LAN interface of the QuadroE1/T1 (see 4.1.2).
3. Remove the default PSTN routing rules from the routing table of the Quadro16x (see 4.1.3). This
is required if the FXO ports on the Quadro16x are not connected to PSTN to decrease call setup
time.
4.1.1 Ensure DHCP server is enabled
1. Log in to the Quadro16x as the administrator.
2. From the LAN services menu, select DHCP Settings for the LAN Interface.
3. Make sure the Enable DHCP Server checkbox is selected and the IP Address Range is
configured (by default 172.30.0.100 – 172.30.0.254, see Figure 1).
Figure 1 DHCP Settings, Quadro16x
PAGE 4 27-Apr-06

4.1.2 Obtain an IP address
To integrate the QuadroE1/T1 into the LAN of the Quadro16x, an IP address from the Quadro16x
LAN IP address range (see Figure 1) must be assigned to the LAN interface of the QuadroE1/T1. Note
that this IP address must not be within the DHCP IP address range of the Quadro16x to ensure no
IP address conflict occurs when adding new IP phones to the LAN of the Quadro16x.
To eliminate the possibility of an IP address conflict on the LAN of the Quadro16x, decrease its
DHCP IP address range by one from the end of the range and click on Save (see Figure 2). Write this
excluded IP address (172.30.0.254) down on a piece of paper and have it handy when configuring
the LAN settings of the QuadroE1/T1. This IP address will be assigned to its LAN interface.
For the configuration of the QuadroE1/T1 LAN settings, the subnet mask of the Quadro16x LAN will
also be required. To view it, open the SystemÆStatus page and click on the Network Status tab
(see Figure 3).

4.1.3 Remove default PSTN routing rules
The scenario outlined in this document assumes that no FXO port on the Quadro16x will be
connected to the service from PSTN, i.e. all outgoing PSTN calls should flow through the E1/T1 trunk
of the QuadroE1/T1.
If this is the case it is recommended either to disable FXO lines on the Quadro16x or remove default
PSTN routing rules from its routing table. Otherwise, the call setup for outgoing PSTN calls may take
longer time. The reason is that the Quadro16x will first try to make PSTN calls using its own FXO
lines and will route the calls to the E1/T1 only after a non-response timeout expires (the timeout
during which the Quadro waits for a dial-tone from the PSTN). This results in an increase in call
setup time.
To decrease call setup time, either disable the FXO lines on the Quadro16x or remove the default
PSTN routing rules from its routing table.
For the first option, select TelephonyÆFXO SettingsÆFXO1 (FXO2) and clear the Enable FXO
checkbox.
For the second option (recommended), follow these steps:
1. From the System menu, select System Configuration Wizard.
2. In the System Configuration Wizard, click on Next until you reach the Emergency
Codes and PSTN Access Code Settings page (see Figure 4).
3. From the PSTN Access Code drop-down list, select the blank space. This will prevent the
Quadro from creating default routing rules for outgoing PSTN calls.
4. Click on Next, then Finish.

4.2 Preconfiguration of QuadroE1/T1
Disable the DHCP server functionality on the QuadroE1/T1 and configure its LAN settings. These can
be done with System Configuration Wizard (see 4.2.1).
4.2.1 LAN settings configuration of QuadroE1/T1
Please note: It is assumed that the QuadroE1/T1 is in its default configuration.
To configure the LAN settings of the QuadroE1/T1
1. Run a browser on a PC locally connected to the LAN interface of the QuadroE1/T1.
2. Enter “http://172.30.0.1” into the address filed of the browser and press Enter.
3. In the displayed Login page of the Quadro, enter admin as the Username and 19 as the
Password to log in as the administrator.
4. From the System menu, select the System Configuration Wizard and click on Next.
5. Enter the IP address and the subnet mask you have marked down (see 4.1.2) into the IP
Address and Subnet Mask text fields respectively (see Figure 5). Click on Next.

7. On the Regional settings and Preferences page, specify Your locale and Timezone
settings and choose your desired GUI theme.
Please note: It is strongly recommended that the regional settings on the QuadroE1/T1
match those on the Quadro16x.
8. Click on Next twice to reach the last page of the wizard, then click on Finish to complete
the wizard.
The QuadroE1/T1 can now be connected to the LAN of the Quadro16x.

6Call Routing Configuration
To allow placing PSTN calls from the Quadro16x to the PSTN via the QuadroE1/T1
•Create a routing rule on the Quadro16x to route PSTN calls to the QuadroE1/T1 (see 6.1).
•Create two routing rules on the QuadroE1/T1 to route calls received from the Quadro16x to
PSTN (see 6.2 ). One of those rules will be used for emergency calls (see 6.2.1), the other for
regular PSTN calls (see 6.2.2).
To allow receiving calls from the PSTN on the Quadro16x via the QuadroE1/T1
•Create a routing rule on the QuadroE1/T1 to route calls from PSTN to the Auto Attendant of
the Quadro16x (see 6.3).

6.2 Routing calls from QuadroE1/T1 to PSTN
According to the rule created in 6.1, calls from the Quadro16x that match the pattern “9*” will be
routed to the QuadroE1/T1. Note that two types of calls fit into this pattern: 1) emergency calls -
the user dials “911”, and 2) regular PSTN calls - the user dials “9+a PSTN number”. Therefore, two
routing rules are to be created on the QuadroE1/T1:
The first - for emergency calls - will route the received calls directly to PSTN (see 6.2.1).
The second - for regular PSTN calls - will discard the first digit (the PSTN access code), and then
route the call (the corresponding digits) to PSTN (see 6.2.2).
6.2.1 Routing emergency calls from QuadroE1/T1 to PSTN
This rule is created in the Local Routing table of the QuadroE1/T1.
1. Log in to the QuadroE1/T1 as the administrator and select Call Routing from the Telephony
menu.
2. On the Call Routing page, click on the Call Routing Table link to display the Call Routing
Table (see Figure 12).

How this rule works: Calls incoming to the QuadroE1/T1 that match the pattern “9*” will be
routed to PSTN after discarding the prefix “9” from their pattern. Note that emergency calls “911”
also match this pattern, but for those calls the previous rule will be used as their pattern has more
matching digits with that rule (see 6.2.1).
