VOICE (Models 8335, 8365, and 8385 only): This profile allo cates enough

bandwidth for one voice call (approximately 80 kbps). If more than one voice

call is placed on the connection using this profile, then the cells will be tagged

(CLP bit set). This profile is policed to 188 cells/sec (enough for one phone

call).

Some numeric values on the ATM Traffic Profiles screen represent cells per

second. An ATM cell is 53 bytes (48 bytes of data plus 5 bytes of overhead), or

424 bits. Conversion guidelines are listed in Table 3-2, Conversion Guidelines.

A voice circuit typically requires 80 kbps, which is 188 cells per second. ATM cells

are 53 bytes in length (a 5-byte header and 48 bytes for payload). After allowing

4 bytes for the AAL2 overhead, you have approximately 44 bytes available for

data. Therefore, the total overhead is 53/44. For a 64 kbps stream, this results in

77.1 kbps (64 x 53/44). The 80 kbps allows extra bandwidth for additional inband

signaling.

The ATM line cards implement Usage Parameter Control (otherwise known as

policing) as described in the ATM Forum’s Traffic Management Specification 4.1

(AF-TM-0121.000). According to this specification, traffic contracts for the two

VBR ATM service categories (rt-VBR and nrt-VBR) include traffic parameters for

Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR). Policing is implemented

using the recommended dual Generic Cell Rate Algorithm (GCRA) funct ions.
