• an integrated feeder node providing fractional T1, E1 and ISDN interfaces with signaling, companding, and super-rate conversion, and line and circuit grooming

Architecture

The 3600 family is built around a range of components that are common to all large multiplexer systems. Universal card slot (UCS) cards provide interface and resource features for all members of the family. Shelves contain either 8 or 16 UCS cards as well as common control circuitry and power supplies. This reduces excess inventory and simplifies craft training across the whole Alcatel line. All Alcatel components are field-upgradable to provide a designed-in migration path as networking applications evolve.

The standards-based, modular architecture of the 3600 consists of one or two 19- or 23-inch (48.3 cm or 58.4 cm) shelves, each with 8 UCS slots, supporting up to 32 T1 or E1 interfaces and a 64 Mb/s, full duplex, non-blocking DS0 switching matrix.

The 3664 multiplexer consists of a single 3600 shelf supporting a full range of voice, data, and resource cards.

The 3600+ Bandwidth Manager consists of a single shelf supporting up to 16 UCS cards or higher bandwidth UCS+ cards, as well as three redundant high speed aggregate cards.

The 3645 High Capacity Bandwidth Manager builds on this modular architecture by connecting up to eight 3600 peripheral shelves and high speed peripheral shelves (HSPSs) to one switching shelf.

The switching shelf is the hub of the 3645; it provides central alarm monitoring, system wide control, and a non-blocking DS0 switching matrix for all peripheral shelves, as well as HSPSs for both one-way (unidirectional and broadcast) and two-way connections. DS3 and dual E3 cards provide copper trunk access and single E3 cards provide copper or fiber trunk access. The 36120 Packet Transfer Exchange (PTE) is built on the proven, standards-based, modular architecture of the 3600 Bandwidth Manager. PTE cards are interconnected by both the 100 Mb/s packet switched FASTbus and by the 64 Mb/s circuit switched shelf backplane bus. Any of the packet-switched cards (FRS, FRE, PTE) can also be utilized in any 3600 family product to provide packet switching capability.

The control card (3600/64/120/+ systems) or switching cards (3645 systems) are optimized to manage DS0, primary rate and data cross-connections that identify frame streams - the shared bandwidth on which permanent virtual circuits (PVCs) are configured.

PTE cards are optimized to switch a PVC segment on one frame stream with a PVC segment on another. The FASTbus provides high speed, fault tolerant, shelf-to-shelf packet switching.

Network management

The Alcatel 5620 Network Manager (NM), formerly the 46020 Network Manager*, allows operators to control transmission network equipment using point-and-click path and parameter configuration. Operators can remotely configure nodes, monitor real-time operations, set up and manage path routes, perform diagnostics and isolate and manage network problems. The center-weighted approach to network management reduces internode control overhead on the network by storing system parameters in a non-volatile configuration database.

When used in a network managed by a 5620 Network Manager, the 3600 family of bandwidth managers allows advanced partitioning capabilities to the time slot level so as to manage congestion, maintain cross-customer security and provision virtual private network services.

Flexible switching

DS0 cross-connect switching is done by the common control circuitry, optimized to provide low transit delays. DSP card-based subrate multiplexing and switching applications supported include: DDS DSOA/ DSOB, I.460 X.50, high capacity multiplexing (HCM) and n*8 kb/s channels. For HCM, the switching resolution is 800 b/s. Packet switching cards can be installed to support high speed switching of multiple frame relay or X.25 channels.

The 36120 provides up to 512 Mb/s switching capacity, over any combination of up to 256 T1/E1, 8 DS3, or 16 E3 interfaces, carrying up to 3,698 frame streams and a total of 126,976 PVCs. This permits hybrid packet and circuit switched services on the same primary rate link.

The 3600+ Bandwidth Manager builds on the architecture of the successful 3600 product by providing wideband/ broadband, SONET/SDH switching functionality (VC/VT) in addition to increased narrowband switching capability. The 3600+ architecture allows for the development of higher bandwidth cards, such as unchannelized T3/E3, and octal T1/E1 to support increasing bandwidth needs and efficiency requirements.

36120 congestion and link management

The 36120 supports:

• threshold alarm levels for mild, severe and absolute congestion of frame streams, PVCs, frame switches, and the FASTbus interface
• forward and backward explicit congestion notification (FECN and BECN) bits
• the discard eligibility (DE) bit
• the user, network, and bi-directional modes of the LMI, ANSI T1.167 Annex D, and CCITT Q.933 Annex A link management protocols

Class of service parameters are fully configurable on a per PVC basis, including committed information rate (CIR), committed burst size (Bc), and excess burst size (Be).

Protection switching

All voice, data, aggregate and subrate aggregates can be preconfigured with a reserved alternate path with immediate diversion (RAPID) to provide fast rerouting of critical information channels. All primary rate interfaces can be configured for card redundancy. DS3 and E3 cards also provide access (link) redundancy. The FASTbus is based on a dual, counter-rotating ring topology that automatically bypasses PTE card or cable failures to maintain system operation.

The 3600+ network protection is provided by a unidirectional path switched ring (UPSR) and 1+1 link redundancy for SONET/ SDH applications and RAPID for network-wide protection of 64 kb/s services.

Voice interfaces

Analog voice channel access is provided through E&M, LGS cards (Loop/Ground Start Subscriber), LGE cards (Loop/Ground Start Exchange), and E&M, LGS, LGE, and manual ring down (MRD) channel units. Both internal and external ringing generators are supported for LGS and MRD interfaces. Digital voice access is provided through T1, E1 or V.35/X.21 PRI aggregate cards. Optional resource cards and modules provide a wide range of voice compression capabilities, including ADPCM, 8 and 16 kb/s HCV, LD-CELP and A-CELP. Alcatel patented stHCV functionality allows transport of compressed voice through tandem switches without any compression/decompression degradation.

Data interfaces

Data devices can be connected directly through V.24/RS232, V.32, V.35, X.21/V.11, RS422 (RS530A, V.36/RS449, X.21, or V.35), OCUDP, 4W T0 or 64 kb/s codirectional interfaces. Remote data devices can be connected through the 2B+D format, V.24/RS232, V.35, and X.21/V.11 interfaces of the Alcatel 2600 or 2700 MainStreet family of data termination units (DTUs).

Aggregate interfaces

Aggregate access can be through channelized, fractional or full T1 or E1 interfaces, T3 or E3 (3645 only), STM-1 and OC-3 (3600+ only), n*64 kb/s, V.35 or X.21 PRI, or 56 kb/s, V.35 or X.21 PRI aggregates.

Resource cards

Resource cards available for the 3600 family include digital signal processing (DSP), data communications processor (DCP), call processor card (CPC), as well as the frame relay switch (FRS), frame relay engine (FRE) and packet engine (PE) for frame relay and X.25 applications.
