This document describes the features and characteristics of the SHD-30/60/120A-CT/cPCI and SHD-30/60B-CT/cPCI/FAX series voice cards produced by Hangzhou Sanhui Information Engineering Co., Ltd. These voice cards support call transfer with China No.1 signaling, No.7 signaling, and ISDN signaling, as well as telephone calling and voice processing functions. They also provide multiple channels of fax resources.
The SHD‑30/60/120A‑CT/cPCI and SHD‑30/60B‑CT/cPCI/FAX series are digital relay voice cards that use a CompactPCI 2.1 bus. Each card can provide 1, 2 or 4 E1 channels, supports Chinese 1‑, 7‑ and ISDN signaling, multiple codec formats, and includes hardware features such as lightning protection and a unique hardware serial number.
The manual is organized into an overview of functions and performance, a block‑diagram of the card architecture, detailed mechanical drawings, system requirements, step‑by‑step installation instructions, hot‑swap procedures, and a full list of technical specifications. Appendices give environmental limits, power consumption, and contact information for technical support. This manual is written in Chinese.
