E1/T1 Settings
The E1/T1 service allows Quadro to be connected to a PBX or to a CO (Central Office) via E1/T1 lines, using E1/T1 CAS/CCS signaling. Quadro
may act as a user or as network. If connected to a private PBX, the Quadro should be configured in the network mode. If an E1/T1 trunk from the
CO is connected to the Quadro, it should be configured as a user.
Please Note: E1/T1 service is available only for QuadroM32x.
The QuadroM32x has one E1/T1 trunk available. The QuadroM32x has no own ISDN trunks and FXO lines, only shared ISDN trunks and FXO lines
are displayed in this page, if available. The shared trunks/lines can be edited from this page. Any changes applied in this page will be automatically
reflected on the ISDN/FXO gateway(s) that share its ISDN trunks and FXO lines.
The E1/T1 Trunk Settings page is used to configure the E1/T1 trunk and the timeslots settings. The page consists of the following components:
The Trunk Settings
table lists the available E1/T1 trunks on the
Quadro and their settings (Trunk name, E1/T1 mode, interface,
signaling types). Clicking on the trunk will open its Signaling
Settings page (Trunk CAS Signaling Settings or Trunk CCS
Signaling Settings
page depending on the selected signaling type)
while selecting the c
orresponding trunk’s checkbox and pressing
Edit will open the Trunk Edit Entry page. E1/T1 Stats link is
displayed for every active trunk on the board and refers to the page
where E1/T1 trunk and traffic statistics can be viewed.
Start and Stop functional links are used to start/shutdown the
selected E1/T1 trunk(s). When E1/T1 trunk is shutdown state, no
E1/T1 calls could be placed and received.

The Trunk Edit Entry page consists of the following components:
The Interface Type drop down list gives an option to choose
between E1/T1 User and Network interface configuration.
The Signaling Type drop down list allows selection of CAS
(Channel Associated Signaling) or CCS (Common Channel
Signaling) sig
naling types. The same timeslot is used both for voice
and data transmission in case of CAS signaling. In the case of CCS
signaling a single timeslot is used for signaling data transmission on
the entire trunk. All other timeslots are used for voice transmission.
The E1 and T1 radio buttons are used to select between E1 and T1
modes. The T1 mode enables 24 timeslots, and the E1 mode
enables 32 timeslots to be used. The selection of E1 or T1 enables
the Line Code, Frame mode, Line Build Out, Coding Type,
LoopBackMode and Clock Mode settings. These settings are
configured to match the E1/T1 settings from the service provider.
Attention: See the Call Routing
chapter to ensure that
modifications to the E1/T1 trunk settings do not lead to broken
routes in the Local Call Routing Table.
