Alcatel-Lucent ISA-ES1 and ES4 Series | Data Sheet 3
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)-4s aggregate 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
c
apacities 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
s
upported.
