Cabling to environment can easily bedone with cable ladders or with raised

floor implementation Cables are directed under raised floor via

cabling cabinet or via side cabling conduit

Optical STM-1/OC-3 cables are directedthrough the CPGO panel

Trunk cables (E1/T1) are directed through

CPET panels on the top of the cabinet andin the cabling cabinet

BSC3i mechanical design


33/42


BSC3i mechanical design

Welded frame structure designed on IEC, EN, ETSI, UL andTelcordia recommendations with advanced features in termsof safety, protection against interference, stability anddurability

Easy transportability and suitability for installations withnormal room height as well as with completed internal

cabling Due to the simple mechanical structure with relatively few

components, the equipment cabinets are easy to assembleand disassemble when necessary

The BSC3i includes forced cooling system to ensureoptimum ambient temperature for its functional units

Nokia NetAct link options


34/42


Nokia NetAct link options

LAN (Ethernet) interface, via LAN connector panel(recommended)

LAN Ethernet interface according to IEEE802.3 forfaster accessThis is the default NetAct link interfaceConnected via CPRJ45 panel on top of the cabinet

Digital X.25 interface, AS7-C(PCM time-slot-based O & M interface via AInterface, G.703)

An O&M interface via transcoders and transmissionequipmentNetwork management interfaces in PCM time slots

Should be used only if LAN is not available

The LAN interface redundancy is implemented byproviding a redundant LAN connection

The digital X.25 interface can optionally be

redundant by using duplicated units

Raised floor installation option

Raised floor installation option

Cabling Cabinet

In equipment rooms with raised floor theCabling Cabinet is used with each BSC3icabinet for cabling external cables underthe floor

Side Cabling Conduit, SCC

The SCC can be used to separate powercabling from the external PCMs cabled tocabling cabinet

The SCC can be installed on either side ofthe BSC
