SIU: QUICK FACTS

› Transmission module for converged RBS sites.

› The Site Integration Unit (SIU) provides common interface between RBSs

(GSM, WCDMA, CDMA, LTE), and IP/Ethernet or IP over

E1/T1 transport networks.

› Facilitates migration from legacy transport (E1/T1) to next

generation high speed transport (Ethernet), while reducing

OPEX through shared transport for 2G, 3G, and 4G radio

standards.

› Enables optimized Abis over IP for Ericsson GSM RBS.

› Bandwidth is dynamically shared between all radio

technologies, optimizing peak capacity for HSPA and LTE

services.

SIU FEATURES

› Aggregates all GSM, WCDMA, LTE, CDMA, and site Local Area Network (LAN) traffic.

› Bundling and unbundling of low-volume traffic and signaling packets to and from the GSM RBSs into

larger IP packets sent to the BSC.

› Ethernet interfaces for connection to an IP based transport network, IP based site equipment and/or

additional IP enabled RBSs.

› Site router functionality with support of configurable static routes to forward traffic between different IP

interfaces created in the system.

› Ability to divide the physical Ethernet into virtual networks distinguished by VLAN IDs.

› Quality of Service (QoS) on the WAN interface for outbound traffic with support of 8 TX queues.

› Basic Metro Ethernet Forum (MEF) support for attachment to MEF provider networks.

› Timing distribution to GSM RBSs through the E1/T1 interfaces and to one co-located RBS through the

clock output interface.

› Support for up to six GSM Transceiver Groups (TG).

› Local management from a console interface or remote management from an Operation Support

System (OSS).

› Support for sixteen E1/T1 interfaces.

› Circuit Emulation Service (CES) over IP network.

SIU Connection

› Logging on remotely

From OSS, connect using SSH. Following a successful log-on, the SIU displays the

Command Line Interface (CLI) prompt through the OSS.

ssh [email protected] password: hidden

OSmon>

› Attaching Local Terminal

1. Connect a configuration cable to the CONSOLE port on the SIU.

2. Configure the local terminal IP address to be on the same subnet as the SIU

(e.g. 192.168.1.9).

3. Enter the following data: telnet 192.168.1.1

username: admin

password: hidden

Recovery actions

› When everything fails…

– restart

– Power cycle (push the button)

– [Replace SIU]

If on site, take a look at the

leds on the SIU.

If blinking rapidly and steady,

it is an indication that the SIU

has gone on cyclic restarts

and it should be replaced.
