The 09400R multiplexer is rack-based with removable plug-in cards such as DS3(E3), Ethernet over SONET (EoS), high density T1 (16/32/64) that support multiple protection schemes. It has 4 OC48 transport connections and can also carry OC3/12/48 connections as tributaries and non-blocking cross-connect at VT1.5, STS1 and STS-3 levels and full add/drop capabilities. The addition of the PTN 10G card gives you multiple 10G and 1G ports that can each independently be configured as Carrier Ethernet or MPLS trunk ports or Ethernet tributaries. In addition to the 100G Ethernet switch fabric you also have a full OC48 of TDM pseudowire switch fabric that connects to the SONET backplane and can carry TDM Services (CEP,CES, SATOP). The G7860A standalone switch gives you the ability to easily add packet transport to and existing networks in a company 1U Chassis. It features the same MPLS and Carrier Ethernet capabilities as the PTN10 card and flexibility in T1 or OC-3 connections via plug in cards to connect to your existing SONET network. The PTN10G card can also be used in the O9500R to allow for10G packet transport, OC48 SONET, DSO interfaces and full cross connect and TDM Pseudowire support all in one box.
