MODU should be installed on the MODU connectors (CN4) of the MBU, and provides an analog modem connection. It supports Bell, ITU-T, V.34, V.32BIS, V.90 Protocol at a speed rate of 300bps up to 33Kbps, and automatic rate negotiation.
CMU50PR (Call Metering-50Hz and Polarity Reversal Detection Unit/NTB415)
The Call Metering-50Hz and Polarity Reversal Detection Unit (CMU50PR) provides 3 Call Metering Detection circuits for 50Hz and provides 3 channels of Polarity Reversal Detection for Call Metering or signaling. It can be installed on the MBU (NTB411), EMBU (NTB412), CHB308 (NTB417), or CSB316 (NTB418).
CMU12PR (Call Metering-12KHz and Polarity Reversal Detection Unit/NTB414)
The Call Metering-12KHz (or 16KHz) and Polarity Reversal Detection Unit (CMU12PR) provides 3 Call Metering Detection circuits for 12KHz (or 16KHz) and provides 3 channels of Polarity Reversal Detection for Call Metering or signaling. It can be installed on the MBU (NTB411), EMBU (NTB412), CHB308 (NTB417), or CSB316 (NTB418).
