J Series Services Routers equipped with a Dual-Port Channelized T1/E1 PIM support
Integrated Services Digital Network (ISDN) Primary Rate Interfaces (PRIs). ISDN PRI,
referred to as S2M in Europe, is the "primary" extended ISDN network interface. It
offers a larger capacity of digital channels utilizing a variety of improved mediums,
and is used by large organizations with intensive communication needs. In contrast,
the ISDN Basic Rate Interface (BRI), known as SO in Europe, provides a limited
number of channels, transmitting over copper wire, and is used by smaller
organizations or individuals with less intensive communication needs. For more
information about configuring ISDN BRI interfaces, see "Configuring ISDN Physical
Interface Properties" on page 873.
Unlike channelized PICs on the M Series and T Series routers, the interface type on
the Dual-Port Channelized T1/E1 PIM is configurable. A single interface can operate
as either a channelized T1 or channelized E1 interface (or clear channel) or as an
ISDN PRI. The ISDN PRI channels can operate on the same interface as T1 or E1
channels. The PIM also supports a "drop-and-insert" feature, allowing you to insert
channels from one port on the PIM into the other port on the PIM.
These ISDN channels are delivered to the user in one of two predefined configurations:
ISDN BRI is configured by specifying properties for a physical ( br- ) interface and
a logical ( dln ) interface.
For ISDN PRI, you configure:
