ULC-1000AN MSAN > Network Interface   Network Interface Gigabit Ethernet interface   > ATMU-GE module The ULC-1000AN ATMU-GE module represents a high-bandwidth, cost-effective network interface for packet based networks. The ATMU-GE is a single slot module with two gigabit Ethernet ports to support high speed internet services, voice over IP (VoIP) and IP television (IPTV) applications. In order to facilitate migration to IPTV, the gigabit Ethernet module also contains hardware support for Internet Group Management Protocol (IGMP). With IGMP proxy support, the ULC-1000AN determines which video streams (in terms of multicast IP addresses) to deliver to which subscribers. To maximize network efficiency, the ATMU-GE module supports link aggregation. Link aggregation not only provides a 2Gbps pipe when needed but also provides increase resiliency if the second port experiences a failure. In addition, the ATMU-GE supports up to 4094 VLANs. > GE-SW module The ULC-1000AN GE-SW module functions as a Gigabit Ethernet switch. There are up to eight 10/100/1000 Mbps Ethernet interfaces in the module, and two of them can be configured as Gigabit Ethernet optical interfaces.     Megaco(H.248)/MGCP/SIP VoIP interface   With the MGU (Media Gateway Unit) module, the ULC-1000AN MSAN acts as the access gateway for connecting conventional POTS telephones with next generation VoIP networks. The MGU module provides a scalable capacity, up to 512 VoIP channels simultaneously. The MGU module complies with Megaco (H.248)、MGCP and SIP standards, and is interoperable with soft switches among different vendors.     V5.2 interface   For PSTN services, V5.2 module is the gateway between the exchange system and the subscriber access network. With 3 million lines deployed in the world wide, the ULC-1000AN MSAN V5.2 module has been in service with switches from various vendors for a long time.     TDM based interface   The ULC-1000AN MSAN provides FXO/FXS、payphone、E&M、ISDN PRA and ISDN BRA modules to interface with central office class 5 switch.     E1 interface   The ULC-1000AN E1X-XCVR and E1TX-XCVR modules provide single E1 and triple E1s uplink interfaces per module, respectively.
