Planning considerations 1643 AM
When planning your system with the 1643 AM, the following items should be
considered:
• Synchronous Capacity – one or two STM-1 or two STM-4 optical aggregate
interface pairs
• Plesiochronous Capacity – sixteen 2 Mbit/s E1 interfaces (basic unit)
– Optional two STM-1 tributary signals (total of sixteen E1 and two STM-1
tributary)
– Optional sixteen additional 2 Mbit/s signals (total of thirty-two E1)
– Optional sixteen additional 1.5 Mbit/s signals (total of sixteen E1s and sixteen
DS1s)
– Optional two 34 Mbit/s signals (total of sixteen E1s and two E3s)
– Optional two 45 Mbit/s signals (for a combination of sixteen E1s and two
DS3s)
– Optional four 2 Mbit/s X.21 signals (for a combination of sixteen E1s and four
X.21s)
– Optional four 10/100BASE-Ts (for a combination of sixteen E1s and four
10/100BASE-Ts)
– Optional twelve SHDSL signals (for a combination of sixteen E1s and twelve
SHDSLs)
– Optional eight Ethernet interfaces in Private Line mode
– 3 x 10/100BASE-TX electrical FE interfaces, 1 x 10/100/1000BASE-T(X)
electrical GbE interface, 1 x 1000BASE-X GbE optical interface via SFP.
• Synchronization: STM-1 or STM-4 aggregate line interface timing or via STM-1o
tributary line or via a 2 Mbit/s data input
• Protection: VC-12/VC-3/VC-4 SNC/N
• Protection: 1+1 MSP (STM-1 interfaces only)
• Operations Systems: remote and local management with Lucent OMS and local and
remote (remote to other 1643 AM) with ITM-CIT, SNMP management is supported
• Three possibilities for Power supply :
– DC (unit contains DC connector)
– AC (unit contains AC connector)
– AC via an external AC/DC connector.
• The 1643 AM provides four miscellaneous discrete inputs (MDIs) which can be
used to read external devices assigned by the customer. Examples are monitoring
temperature, humidity, open doors, etc.
The equipment provides four miscellaneous discrete outputs (MDOs) which can be
used to drive external devices assigned by the customer. Examples are signaling
