T1 PRI For PBX Telephony
A T1 PRI, also called an ISDN PRI, is a "Primary Rate Interface"
providing 23 individual digitized telephone lines plus data such
as Caller ID on a single digital telephone trunk line. A PRI line
is usually much less expensive than a dozen or more analog business
Digital Signage Bandwidth Options
Digital signs, including large billboards, are easily and instantly
updated with data downloads. T1 and fractional T1 lines or VSAT
digital satellite connections are available even in rural areas.
Channelized T1 vs ISDN PRI
T1 lines can support two protocols of switched circuit telephony.
Channelized T1 lines offer 24 phone lines using in-band signaling.
ISDN PRI, or Primary Rate Interface, offers 23 phone lines and
common channel signaling that can include data such as ANI Automatic
Number Identification or Caller ID.
T1 Digital Cross Connect Systems
A digital cross connect system, often abbreviated DCS or DCAS,
allows you to switch traffic among your T1 lines. It will even
reach into the line to connect individual channels or timeslots
rather than the entire circuit. A manual device that cross connects
T1 lines is called a DCX or patch panel.
Advantages of Managed IP Services
Managed IP is a WAN or Wide Area Network service that is provided
and managed by a competitive carrier that owns and operates its
own IP network. A managed IP provider ensures that you have the
bandwidth and connectivity you need, without having to manage
the WAN yourself.
