Alcatel-Lucent manual ISA-ES1, delivering 1 x VC-4 aggregate bandwidth, Transported bandwidth

Policing parameters are specified according to:

•Committed information rate (CIR)

•CIR burst window size (CBS)

•Peak information rate (PIR), or excess information rate

•PIR burst window size (PBS)

Supported SLAs in ES1 and ES4:

•Guaranteed traffic

•Best effort traffic

•Regulated traffic

The Alcatel-Lucent ISA-ES1 and ISA-ES4 modules support one (1) and four (4) virtual container (VC)-4saggregate trunk-

ing capacity respectively (see Figure 4 and Figure 5). The ISA-ES1 supports three (3) or eight (8) E/FE ports and the ISA-ES4 supports eight (8) E/FE ports and one (1) GigE port. The ISA-ES modules can be configured to support a wide range of VC-12, VC-3 and VC-4 combinations for flexible, full featured Ethernet over SDH. Figure 6 charts the aggregate bandwidth transported for various VC-X x Nv VC concatenation combinations on an ISA-ES. Table 1 presents a detailed view of the ISA-ES capacities in terms of maximum VC- 12/3/4, VC groups (VCG) by VC-12/3/4 and VC-12/3/4 per VCG.

Hosting from one to several ISA-ES cards, the possible OMSN equipment configurations are outlined in Tables 2 and 3. The total number of Ethernet (Eth)/FE per node is directly related to the number of hosted ISA cards. Where larger quantities of Eth/FE ports are required, the Alcatel-Lucent 1850 Transport Services Switch (TSS) family is an ideal fit. Tables 4 and 5 present a detailed view of the available ISA-ES modules and the Alcatel-Lucent OMSN equipment on which they are supported.
