5.12 CE-100T-8 Card
Note For hardware specifications, see the “A.7.6 CE-100T-8 Card Specifications” section on page A-50.
The CE-100T-8 card provides eight RJ-45 10/100 Mbps Ethernet ports and an RJ-45 console port on the
card faceplate. The CE-100T-8 card provides mapping of 10/100 Mbps Ethernet traffic into SONET
STS-12 payloads, making use of low-order (VT1.5) virtual concatenation, high-order (STS-1) virtual
concatenation, GFP, and point-to-point protocol/high-level data link control (PPP/HDLC) framing
protocols.
The CE-100T-8 card also supports the link capacity adjustment scheme (LCAS), which allows hitless
dynamic adjustment of SONET link bandwidth. The CE-100T-8 card’s LCAS is hardware-based, but the
CE-100T-8 also supports SW-LCAS. This makes it compatible with the ONS 15454 SDH ML-Series
card, which supports only SW-LCAS and does not support the standard hardware-based LCAS.
SW-LCAS is supported when a circuit from the CE-100T-8 terminates on the ONS 15454 SDH
ML-Series card.
The circuit types supported are:
• HO-CCAT
• LO-VCAT with no HW-LCAS
• LO-VCAT with HW-LCAS
• STS-1-2v SW-LCAS with ML only
Each 10/100 Ethernet port can be mapped to a SONET channel in increments of VT1.5 or STS-1
granularity, allowing efficient transport of Ethernet and IP over the SONET infrastructure.
Figure 5-11 shows the CE-100T-8 card faceplate and block diagram.
