Product Description
The E-PRI Cassette provides the interface for connection of one E-PRI line of up to 30 channels from the public network provider. E-PRI is a European protocol used by all network providers and provides a Primary Rate Interface (PRI) which consists of a 2 Megabit pipe (a digital connection). The pipe consists of 30 Bearer channels. Each bearer channel provides 64K/bit of bandwidth, each channel being the equivalent of one trunk line. 32 channels x 64K/bit = 2,048 bytes, hence the name 2 Megabit (or 2 Meg).
The Euro ISDN interface is also referred to as DSS1, Q931 or I421
