In addition to advanced and comprehensive telephony services that are provided by the TGM550, the Juniper J-series Router, either the J4350 or J6350, provides full data networking services, precluding the need for a WAN router. The J-series routers use Juniper Physical Interface Modules (PIMs) for the hardware components to support network and routing features. The J-series routers also provide Ethernet connections to a separate Ethernet switch that IP phones connect to.
The IG550, through its use of the TGM550 and TIMS, supports the following features:
- Traditional telephones and trunks. In particular:
- Two built-in line ports to support two analog telephones or incoming analog DID trunks on the TGM550
