Product Summary
The PEB2245 is a Multipoint Switching and Conferencing Unit (MUSAC) that combines a time switch unit (MTSC) and a powerful signal processor on one chip. The PEB2245 enhances the capabilities of a PBX by supporting teleconferencing and multipoint data communication over voiceband channels. Digital signal processing techniques are used to implement the conferencing algorithms. Up to 64 channels of the 512 incoming PCM channels may be manipulated by the signal processor and output to any of 256 outgoing PCM channels. All functions of the PEB2245 are programmed and controlled via an 8-bit standard µP interface (Motorola or Intel type).
Parametrics
PEB2245 absolute maximum ratings: (1)Ambient temperature under bias TA: 0 to 70℃; (2)Storage temperature Tstg: – 65 to 125℃; (3)Voltage on any pin with respect to ground VS: – 0.4 to VDD + 0.4 V; (4)Maximum voltage on any pin Vmax: 7V.
Features
PEB2245 features: (1)Time/space switch for 2048-, 4096- or 8192-kbit/s PCM systems; (2)Switching of up to 512 incoming PCM-channels to up to 256 outgoing PCM channels; (3)16 input and 8 output PCM lines; (4)Different kinds of modes (2048, 4096, 8192 kbit/s or mixed mode); (5)lConfigurable for primary access and standard applications; (6)lProgrammable clock shift with half clock step resolution for input and output in primary access configuration; (7)Configurable for a 4096- and 8192-kHz device clock; (8)Tristate function for further expansion and tandem operation; (9)Tristate control signals for external drivers in primary access configuration; (10)2048-kHz clock output in primary access configuration; (11)Space switch mode.
