  1. Principles of Voice & Data Integrated Services Digital Network -- ISDN Bellevue Community College Bob Young, Instructor

  2. Channel Structure Bearer Service -- 64 Kbs Data Channel -- 16 Kbs Overhead -- 48 Kbs

  3. Service Levels • Basic Rate Interface (BRI) • 2 Bearer Services plus 1 Data Channel • (2B+D) • Linking (Bonding) of Bearer Services • Primary Rate Interface (PRI) • 23 Bearer Services plus 1 Data Channel • (23B+D) • Linking (Bonding) of Bearer Services

  4. Let's Do the Math… • 2B+D = (2 x 64) + 16 = 144 Kbs • With overhead: 2B+D+O = (2 x 64) + 16 + 48 = 192 Kbs

  5. The Data Channel At the PRI level, a single 16 Kbs Data Channel can support multiple T1's with 24 Bearer Services each.

  6. "Parts" and Service • ISUP • Integrated Services User Part • SCCP • Signaling Connection Control Part • TCAP • Transaction Capability
