The Quad E1 card is set up and used in a similar way to the G.703 option card. Following
selection of the Quad E1 card as the terrestrial interface via the
Edit-Unit-Interface-
Terrestrial
screen (Section 7.3.3.3.2), two menus (
Edit-Tx-Interface
, Section 7.3.3.1.8 and
Edit-Rx-Interface
, Section 7.3.3.2.9) can be used to set up the Tx and Rx paths,
respectively, of each port of the Quad E1 card.
The P3706 Quad E1 interface card not only provides all the above functionality, but if the
MultiMux (
Mux
SAF) feature has also been purchased and enabled, then G.703, serial
data and IP traffic may be multiplexed together to form one aggregate satellite carrier.
Multimux is explained in a separate document ‘Multimux Data Multiplexer Option’
(application note 205348) available in the Evolution modem documentation area of
http://paradisedata.com
. It allows up to two E1s to be amalgamated with up to 2Mbps of
IP and up to 2Mbps of EIA530 onto a single carrier. Up to three E1s can be used if
amalgamating only one of IP or EIA530.
6.2.6 Eurocom D1 Option Card
There are two versions of the Eurocom option card.
The P300-compatible Eurocom D1 option card (part number P3709) provides a
•
Eurocom
D interface, data rates of 16 to 2048kbps, AMI coding, Eurocom G interface at 16 or
32kbps on a 25-pin D male connector.
The Eurocom D1/EIA530 option card (part number P3713) provides Eurocom D interface,
data rates of 16 to 2048kbps, Eurocom G interface at 16 or 32kbps as well as EIA530
signals on the same connector, supporting RS422, X.21, V.35, RS232 and balanced
G.703. It uses a 25-pin D female connector.
6.2.7 IP Traffic Option Card
An Ethernet traffic interface is always available on the base modem as detailed in Section
6.5. This provides a basic level of IP operation (typically it can handle up to 5Mbps of
UDP data or 10Mbps of TCP data).
For more demanding applications, the IP Traffic option card (part number P3714)
supports TCP acceleration up to the maximum data rate for the modem (compared to the
base modem acceleration of up to 10Mbps) via two RJ45 Ethernet 10/100/1000 (GigE)
BaseT connectors. The card supports up to 5000 concurrent TCP connections and
typically achieves bandwidth utilization of around 90%. It also supports HTTP
acceleration, which downloads typical web pages up to 30% faster on average.
The IP Traffic card can handle up to 50 000 packets per second, compared to the IP
processing built into the base modem, which has a limit of 10 000 packets per second).
The IP Traffic card automatically selects speed and duplex but these can also be
controlled via the menus.
Bridging, static routing and dynamic routing are all supported on both the base modem or
the IP traffic card, depending on what is fitted.
