The PM4358 COMET-OCTAL device is an Eight-channel T1/E1/J1 framer with integrated analog Line Interface Unit (LIU). The COMET-OCTAL provides a common Framer and LIU solution platform for all major worldwide formats. In a compact 17mm by 17mm package, the device provides complete line side integration, software-selectable redundancy for 1:1 protection, software-selectable framing for three global primary rate framing formats (T1/E1/J1) and support for short-haul and long-haul analog line interfaces. The COMET-OCTAL enhances system reliability by enabling customers to implement software selectable 1:1 protection for redundant applications with no additional board components. In a redundant application, a standby T1/E1/J1 interface is used to protect an active link, allowing a quick recovery in case of line failures. The device also autonomously generates periodic performance reports, which reduce the software overhead associated with meeting T1 Standards in high-density designs.
