Drop-And-Insert Modules; Standards Supported By The Drop-And-Insert Modules; Using An E1- Or T1-Carrier Line For Data And Voice - HP ProCurve 7000dl Series Basic Management And Configuration Manual

Using an E1- or T1-Carrier Line for
Data and Voice
You may be able to lower your data communications and telephone costs by
leasing an E1 or T1-carrier line and using some of the bandwidth for data and
some of the bandwidth for TDM (or traditional) voice. You will then have an
affordable WAN solution or Internet connection, and depending on your
existing telephone setup, you may have additional phone lines as well. This
solution is particularly attractive for small-to-medium businesses (SMBs).

Drop-and-Insert Modules

If you want to use your E1- or T1-carrier line for both data and voice, you must
purchase and install a drop-and-insert module for the ProCurve Secure Router.
These modules are called drop-and-insert modules because they pass, or drop,
some of the bandwidth from the E1- or T1-carrier line into a private branch
exchange (PBX).
Two drop and insert modules are available for the ProCurve Secure Router:
E1 + G.703 module
T1 + DSX-1 module
If you live in Europe, South America, Australia, or Asia (except Japan), and
can lease an E1-carrier line for your WAN connection, you should purchase
and install the E1 + G.703 module. If you live in the United States or Canada,
and can lease a T1-carrier line for your WAN connection, you should purchase
and install the T1 + DSX-1 module. If you live in Japan, you will need to check
with your Public Telephone and Telegraph (PTT) authority because many
PTTs in Japan offer T1-carrier lines for data. For voice, however, these PTTs
offer J1-carrier lines.

Standards Supported by the Drop-and-Insert Modules
