[M: *xx] - alternate code used for MLVP (multi-line variety package) by Telcordia Technologies, (formerly Bellcore). It goes by different names in different RBOCs. In Bellsouth it is called Prestige. It is an arrangement of ESSEX like features for single or small multiple line groups. The reason for different codes for some features in MLVP is that call-pickup is *8 in MLVP so all *8x codes are reassigned *5x
