ISDN 2
|
- Basic Rate = 2 x 64Kbps
- 2B+D = 2 Channels of 64K also referred to as “Bearer” channels and 1 referred to as “Data” or
signalling Channel of 16K.
- Total bandwidth is 128K.
|
| |
ISDN 30
|
- Primary Rate = 32 x 64Kbps
- 30B + 2D Protocols: DASS II, DPNSS & ETSI Q931
- 32 Channels = 30 Channels of 64K referred to as “Bearer” Channels & 2 referred to as “Data”
or signalling Channels.
- Total bandwidth of approximately 2 Megabits.
|
| |
Notes
|
Total number of bits available = 2,048,000 - ie: 32 x 64 - ie 2 Meg.
