VCL100XP Expansion Chassis

• The power supply units and expansion controller cards on VCL100XP can be optionally redundant


Slide 7


Power Supply Card (PSU) This module supplies power to all cards on STM-

1/4– Generates standard 3.3 volts based on – 48

Volts D.C input– All other required voltages are generated on the

cards themselves using converters This module can be optionally redundant The module is hot-swappable and hot-insertible Provision of over-voltage and under-voltage

protection for specified supply ranges Additional functions include temperature

monitoring, power control


Slide 8


Management Interface Card (MIC) This card supplies the management interfaces

for both local and remote management– RS-232 port for local management– 10/100 Ethernet port for remote management

The card provides status LEDs for alarm outputs Potential-free contacts for alarm extension or

taking in ambient alarms BITS synchronization inputs and outputs are

provided on the card Overhead channels such as order-wire and F1

user byte can be accessed using MIC


Slide 9


Processor Sub-System (PSS) This card serves as the central controller for the

complete STM-1/4 system Based on a powerful processor, Motorola

PowerPC 860, supplemented by 64MB SDRAM and 128MB Flash

Main OS is loaded on a 128MB compact flash disk

The card can be optionally redundant ensuring that provisioning happens even when one PSS has failed

The card is not traffic-affecting viz., traffic remains unaffected in spite of PSS failure(s)


Slide 10


VCL100 MSPP: Redundancy Features

VCL100 STM-1/4 has no single point of failure; it supports a wide range of redundancy and availability features

The following common units can be optionally redundant – Power Supply Unit (PSU)

1+1 hot standby and load-sharing modes– Cross-connect Unit (XC)

1+1 hot standby The slave XC is always kept in sync with the master XC to reduce

switching time if the master fails– Processor Sub-System (PSS)

PSS module is non traffic-affecting; provisioned traffic remains unaffected even if both modules fail

1:N equipment protection for E1/DS1 tributaries– N<=3


Slide 11


VCL100 MSPP:Network Protection

VCL100 STM-1/4 supports standard network protection schemes defined in ITU-T G.783 and G.841

– SNC-I, SNC-N, 1+1 MSP/APS Support for new mesh based protection schemes which are more

bandwidth efficient– Diverse Mesh, Shared Mesh

Support for mesh-based architecture– Mesh is rapidly replacing rings in new network architectures– Mesh architecture is more flexible, bandwidth-efficient and reliable

compared to rings– Mesh is future-proof

Mesh-restored circuits – Circuits are rerouted using OSPF/MPLS upon link/node failure– Increases bandwidth efficiency by avoiding the bandwidth duplication

of ring-based protection


Slide 12


VCL100 MSPP:Management Features

VCL100 STM-1/4 uses an IP overlay over SDH overhead bytes to carry management information

– Uses standard Layer 3 routing protocol, OSPF for routing management information

VCL100 STM-1/4 provides multiple communication channels for carrying management information

– D1 to D3 bytes (DCC-RS)– D4 to D12 bytes (DCC-MS)– F2/F3 path overhead bytes– Ethernet to E1 mapping

E1 management channel can be physically accessed using the 28xE1 tributary card


Slide 13


VCL100 MSPP:Management Features

In addition, the platform supports a DCC transparency feature allowing it to be deployed in mixed vendor scenarios

– eg., if the alien equipment uses D1-D3, VCL100 STM-1/4 can use D4-D12 with pass-through of D1-D3 bytes

E1 mapping saves additional equipment and optical ports while introducing VCL100MC4 in incumbent networks with alien equipment

– Since connectivity between VCL100MC4 and the alien equipment can be through E1s rather than wasting additional STM-1 interfaces

VCL100MC4 provides support for up to 12 In-Band Channels (IBC) and one E1 management channel

– The maximum data rate per node is 4 Mbps


Slide 14


Inter-working with third-party equipment:Example

• The existing third-party equipments of the customer use DCC-M bytes for their management; VCL100s make use of the E1 management channel

• Alien equipment and VCL100’s co-exist on the same ring and seamlessly inter-work

ETC solution on VCL100 STM-1/4 The ETC (Ethernet Tributary Card) is a tributary module on

VCL100 STM-1/4 – The module supports eight 10/100 Base-TX ports with support for

auto-negotiation An ETC can be operated in either of the following mapping

modes for transport over SDH – Ethernet over SDH mode: This involves the mapping of Ethernet

traffic to multiples of VC-12s up to one STM-1 equivalent per card Compliant to recent ITU standards on Ethernet over SDH (EoS)

– Ethernet over PDH mode: This involves the mapping of Ethernet traffic to multiples of E1s using Multi-Link PPP

Compliant to IETF rfc 1990 on ML-PPP and rfc 1662 on “PPP in HDLC-like framing”

Also supports an option to directly map Ethernet traffic to E1s without further mapping to SDH for access router apps


Slide 16


ETC solution: Salient Features ETC supports the following Ethernet over SDH framing standards

to enable inter-connection of Ethernet LANs over an SDH network:

– Ethernet over LAPS standard as per ITU-T X.86– Ethernet over PDH using ML-PPP/PPP/HDLC as per IETF rfc 1990

and rfc 1662– Ethernet over GFP as per ITU-T G.7041 in the frame-mapping mode

ETC allows efficient mapping of “tagged” and “untagged” Ethernet traffic into SDH virtual containers

It is possible to flexibly map data traffic arriving on any Ethernet port to one or multiples of VC-12s, VC-3s, VC-4s (n X VC-12s/VC-3s/VC-4) where n=1,2…63 for VC-12s, n=1,2,3 for VC-3s and n=1 for VC-4.


Slide 17


ETC solution: Salient Features

The bandwidth allocated to a given port, in multiples of VC-12s, is software configurable

It is possible to configure the ETC in Ethernet over SDH or Ethernet over PDH (ML-PPP) mode

– Ethernet over SDH: Either GFP or X.86 mode on a per-card basis ETC supports PAUSE frames as per IEEE 802.3x for flow control ETC supports port aggregation that enables aggregation of traffic

from multiple source ports to the same exit port thus saving expensive ports on the destination router/switch

Each ETC currently provides one STM-1 equivalent of upstream bandwidth.


Slide 18


ETC solution: Salient Features

Ethernet over PDH supported for carrying traffic over a network with a mix of SDH and PDH

– Framing as per the following IETF draft rfc 1662: PPP in HDLC-like framing

– Mapping to multiple E1 circuits as per the following IETF draft rfc 1990: The PPP Multi-link protocol (MP)

– IEEE 802.3x for flow control of incoming Ethernet data
