Multi-Service PCM Multiplexer
NIM-120P

The NIM-120P is a PCM MUX device with high qualities, providing multiple services for customers through 1 or more E1 links. NIM-120P provide at most 4 E1 links(G.703 standard)for voice, data, video etc transmission. All time slots can be assigned freely for any service port.
Service Cards including: FXS/FXO card, 2/4-line E/M card, OW card, EM2/4 audio card, magnetic-stone telephone card, 2100Hz magnetic-stone relay card, V.24/V.28 card, ITU G.703 64K card, baseband relay card, X.50/X.58 card, V.35/V.11 card, and 10BaseT card etc.
NIM-120P is widely used in PSTN, banks, police offices, and many other private networks.
