SRAL XD Physical Interfaces Description IThe IDU Controller Unit acts as an IP router able to route all the IP packets towards the NMS trough the following management interfaces: interfaces: R channel: Reserved 64 Kbps (full duplex) synchronous contra-directional channel embedded into the radio channel: duplex) contraframe D-ext: 64 kbit/s synchronous co/contra-directional channel available trough V.11 external interface of the ext: kbit/s co/contraSRAL XD Access Unit. It can be used as alternative to the D-embedded channel D-embedded: 64 kbit/s synchronous contra-directional channel embedded into a selected time slot of the 2 embedded: kbit/s contraMbit/s Mbit/s tributary signal. It can be used as alternative to the D-ext channel signal. Q-LAN: LAN 100BaseT Ethernet interface used for transmission of management information between the coLAN: colocated SRAL XD NEs and the Management System. It can be used as alternative to the V-bus channel V-LAN: LAN 10BaseT Ethernet interface used for daisy chain connection of co-located SRAL XD NEs. It can LAN: cobe used as alternative to the V-bus channel



SRAL XD Physical Interfaces Description IIV-BUS: RS-485 interface (128 Kbps Half Duplex) used for daisy chain connection of co-located SRAL XD NEs BUS: RScoQ/Vand SRAL NEs. It can be used as alternative to the Q/V-LAN interface. This interface is only available for SRAL XD Plug-in from SVR 3.5 onward. PlugRS-232: RSRS-232: RS-232 Serial Interface for LCT connection. It can also be used for interworking purposes. All the above management interfaces uniquely identified by the IDU Controller IP address and support the RIPv1 or OSPF routing protocol.

Auxiliary Channel: User Channel: 64 Kbps synchronous data channel for user defined applications. It can be used to transport Channel: transparently the management information of 3rd party equipment over the Siemens Radio towards the NMS. This 64 Kbps is externally available through V.11 interface configurable as either contradirectional or cocodirectional mode.
