Primary Rate Interface (PRI) Card
ISDN PRI in North America supplies 23 B-channels (bearer channels) plus one D-channel (data
channel). PRI in Europe supplies 30 B-channels plus one D-channel. Each channel is capable
of transmitting voice or data calls at 64 Kbps. PRI is commonly referred to as 23B+D or 30B+D.
Each PRI card has two links, either T1 for the Dual Port T1 (Universal T1) card in North America
or E1 for the Dual Port E1 (Universal E1) card in Europe. The card occupies one DSU card slot
and allows another DSU card (including another PRI card) to be installed in the slot beside it
on the same FIM. The PRI card is hot-swappable.
The PRI card is configured with Network-side termination (NT) as the default. There are two
jumper positions for each circuit; one for NT and one for Line-side termination (LT). To set the
card for LT, remove the jumper blocks from the NT position and place them on the LT position.
The connections to and from the PRI card are made through an Interface Assembly mounted
at the back of the DSU cabinet. These connections include:
• two T1 or E1 interfaces for network connection (T1 = RJ-45 connectors) (E1 = RJ-45 or
coaxial connectors)
• an RS-232 port (DB9 connector) for administration and debug
• an Ethernet port (RJ-45 connector) for future use
