Notes: 1. PDU size in cells is computed based on ceiling( ( PDU size in octets + 16) / 48). This assumes an 8 octet LLC/SNAP header and an 8 octet AAL/5 trailer. 2. Due to the number of possible configurations, IMA pps rates are not listed, but may be derived from the following formula: floor (IDCR/cells per packet), where cells per packet is computed as in note 1. 3. The following cell rates were used: DS-1 = 3622 cps (using ATM TC) E1 = 4681 cps 25.6 Mb/s = 60377 cps E3 = 80000 cps (using ATM TC) DS-3 = 104266 cps (using ATM TC) OC-3c = 353207 cps OC-12c = 1412828 cpsAppendix C: PDU's
