Quantity:

The DASS II Cassette provides the interface for connection of one DASS II line of up to 30 channels from the public network provider. DASS II is a UK standard protocol used by all network providers and is provided on a Primary Rate Interface (PRI) which consists of a 2 Megabit pipe (a digital connection). The pipe consists of 30 Bearer channels 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). DASS II circuits are commonly referred to as digital trunks.
The cassette is available in three variants: 30, 15 and 8 channel options. The UK tariffs for digital trunks enable a user with an eight line requirement to install DASS II more cost effectively than an analogue option. Thus the smaller user can now access all the benefits of a digital service, eg. DDI (Direct Dialling In).
