ZXWR RNC Product Characteristic
High integration, large capacity, full
configuration of one million subscribers
needs only two racks.
All-IP configuration, various interfaces
Support ATM/IP dual protocol stacks.
Reduce the transp ort reso urc e by ATM-IP gateway
funct ion.
Easier evo lut io n to al l IP UTRAU by the rich
int erfaces su ch as IP ov er E1, ATM over E1/STM-1,
IMA E1/ch annelized STM-1, POS, FE, GE etc.
