Shelf description

Overview

Alcatel-Lucent 1850 TSS-5 is a single-shelf multiplexer that offers the following capabilities:

• The VLNC50/52/55 SONET/SDH Transport circuit pack and the VLNC35 Fast Ethernet Private Line circuit pack are controlled by, and require, a VLNC2 System Controller in the SYSCTL slot.

• DS1 and DS3 signals can be multiplexed over OC-3, OC-12, OC-48 lines, and E1 and E3 signals over STM-1, STM-4, STM-16 lines. The VLNC50/52/55 circuit pack must be installed in the MAIN1 (and optionally MAIN2 slot), equipped with the required pluggable transmission modules, and be provisioned for the desired signal rate.

  When UNPROT (protection-not-allowed), the two lines on the same board (OC-3/STM-1 or OC-12/STM-4) must be the same rate and may be either 0x1 (default) or UPSR/SNCP.

  When PROT (equipment-protection-allowed), each pair of lines across the boards may be a different rate and may be either 0x1, 1+1, or UPSR/SNCP. The two pairs of lines can have different applications.

• Fast Ethernet or Gigabit Ethernet optical connections, depending upon the type of pluggable transmission modules in the VLNC40/42/42B circuit pack installed in the MAIN 2 slot.

• Ethernet aggregation of up to 20 10/100BASE-T Electrical Ethernet ports onto Gigabit or Fast Ethernet links using the VLNC40/42/42B circuit pack in the MAIN 2 slot.

• Circuit emulation of DS1/E1 signals over Ethernet and off-load of DS1/E1 ML-PPP data traffic for transport over Ethernet, using the VLNC60/61/62 circuit pack.

• Circuit emulation of DS1/E1 signals over Ethernet and a channelized OC-3/STM-1 line, using the VLNC64 Circuit Emulation Mini-hub circuit pack in the MAIN 1 or MAIN 2 slot.

• Data off-load for Ethernet back-haul from remote wireless locations, using the VLNC60/61/62 circuit pack.

• The VLNC40/42/42B Ethernet Aggregator, VLNC60/61/62 Circuit Emulator, and VLNC64 Circuit Emulation Mini-hub circuit packs operate independent of the SYSCTL circuit pack and are self-managed.

The VLNC2, VLNC40, VLNC42/42B, VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, and VLNC64 circuit packs are compatible with the Alcatel-Lucent 1850 TSS-5 High Capacity shelf.

Shelf description

Alcatel-Lucent 1850 TSS-5 contains 1 Function Group C slot, 2 Main slots, and one CTL slot.

Function Group C slot

The Function Group C slot is designed to house a Fast Ethernet Private Line circuit pack (VLNC35, or a 3-port Fast Ethernet circuit pack VLNC33). The slot is mapped directly to four RJ-45 connectors, labeled for GRP C, on the VLIU(1,2,10) interface unit. The VLNC33 must be used in conjunction with a VLNC42B circuit pack in Main2; the VLNC33 is not supported if any other pack is installed in the shelf other than the VLNC42B in Main 2. If a VLNC35 circuit pack is installed, the control slot must be equipped with a SYSCTL VLNC2 circuit pack and M1 and/or M2 must be equipped with a VLNC5x SONET/SDH Transport circuit pack. A 199SC Apparatus Blank must be installed if the slot is unequipped.

Main slots (MAIN 1 and MAIN 2)

The MAIN 1 and MAIN 2 slots are reserved for the VLNC40, VLNC42/42B, VLNC50, VLNC52, VLNC55, VLNC60, VLNC61, VLNC62, and VLNC64 circuit packs. They provide the optical links from which bandwidth can be mapped to support the lower bandwidth TDM and packet interfaces on the shelf. The SMC/SEC (±20 ppm) timing generator and main TDM switch fabric is embedded in the VLNC50/52. The Stratum 3 (±4.6 ppm) clock and main TDM switch fabric is embedded in the VLNC60/61/62 and VLNC64 circuit packs.

The VLNC40/42/42B circuit pack is supported in the MAIN 2 slot.

The VLNC50/52/55 circuit pack is supported in the MAIN 1 slot and MAIN 2 slots.

The VLNC60/61/62/64 circuit pack is supported in the MAIN 1 and MAIN 2 slots.

A 199MN Apparatus Blank must be installed in any unused Main slot.

Control slot

The CTL slot is reserved for the non-redundant VLNC2 System Controller (SYSCTL) circuit pack. The System Controller provides control and communications functions with the VLNC50/52/55 SONET/SDH Transport circuit pack and the VLNC35 Fast Ethernet Private Line circuit pack. The VLNC5x and VLNC35 circuit packs require a VLNC2. The SYSCTL circuit pack also provides a serial RS-232 port and an 100-bps Ethernet LAN port that support WaveStar^® CIT operations. A 199SC Apparatus Blank must be installed in an unequipped CTL slot.

Fan unit

The Alcatel-Lucent 1850 TSS-5 High Capacity rack-mount shelf contains a plug-in fan unit.

Circuit pack blanks

Any unused slot in the Alcatel-Lucent 1850 TSS-5 must be equipped with an appropriate circuit pack blank in order to meet radiated emission requirement per GR-1089.

A 199MN Apparatus Blank must be installed in an unused Main slot.

A 199SC Apparatus Blank must be installed in an unequipped Function Group C slot and an unequipped CTL slot.

VLIU(1,2,3,10) interface unit description

The Alcatel-Lucent 1850 TSS-5 shelf provides the following connections on the VLIU(1,2,3,10) interface unit:

• 2 pairs of positive and negative connections (VA and VB) for −48 VDC or +24 VDC power.

• 2 power-on LEDs (PWR-A and PWR-B), located on the front of the fan unit in the High Capacity rack-mount shelf.

• DS3/E3 coaxial ports: two sets of backplane DS3/E3 ports that are routed to the 3 pairs of DS3/E3 connectors on the faceplate (does not apply to the VLIU3)

• RJ-45 connectors (GRP A)

  • VLIU1: 8 ports (1–8), mapped to the MAIN slots and supported as DS1/E1 ports by a VLNC50, or as DS1/E1 ports by a VLNC60. The VLIU1 supports an unprotected or protected VLNC50 or VLNC60, and can also support a VLNC40/42/42B.

  • VLIU2: 28 DS1 ports (1–28) or 21 E1 ports (1–21), mapped to the MAIN slots and supported as DS1/E1 ports by a VLNC52/55 or VLNC61 circuit pack. The VLIU2 supports an unprotected VLNC50/52/55, VLNC60, VLIU61, VLIU62, or VLNC64 and can also support a VLNC40/42/42B and/or a VLNC64.

  • VLIU3: 16 DS1 ports (1–16) or 16 E1 ports (1–16), mapped to the MAIN1 slot and supported as DS1/E1 ports by VLNC62 circuit pack. The VLIU3 supports an unprotected VLNC60, VLIU61, VLIU62, or VLNC64 and can also support a VLNC40/42/42B and/or a VLNC64.

  • VLIU10: equipment-protected 28 DS1 ports (1–28) or 21 E1 ports (1–21) mapped to the MAIN slots and supported as DS1/E1 ports by VLNC50/52/55 circuit packs, in MAIN 1 and 2 slots. The VLIU10 supports VLNC50/52/55 equipment protection. The VLIU10 can also support VLNC60, VLNC61, and/or a VLNC64. The VLIU10 does not support the VLNC40/42/42B.

• 20 10/100 Mb/s Ethernet ports are mapped to MAIN 2 and supported by the VLNC40/42/42B.

  • On the VLIU1, these ports appear on RJ-45 jacks numbered 9–28

  • On the VLIU2 and VLIU3, these ports appear on RJ-45 jacks numbered 41–60.

    On the VLIU3, the 20 FE ports are consolidated into 10 RJ-45 faceplate jacks (down from 12 jacks in VLIU2). Ports 49/51 and ports 50/52/55 are combined. 2:1 breakout cables (same as those used for VLIU2 FE ports) are needed to obtain access to the second group of ten FE ports.

• On the VLIU3, the two recovered RJ-45 jacks (from previous item) are combined with the four recovered C-Group RJ-45 jacks (following item), to form a new group of six Time of Day ports for use with the VLNC62 circuit pack. These occupy the right-most six positions of the right-most 16-jack block. The three upper jacks are connected to M1. The lower three jacks are connected to M2.

• On the VLIU1, VLIU2, and VLIU10: 4 Ethernet ports, mapped directly to the Function Group C slot.

• 2 RJ-45 connectors for RS-232 management connections to any packs in the MAIN 1 or MAIN 2 slots that are not managed by the SYSCTL circuit pack.

• Connectors for 4 miscellaneous discrete input (MDI) and 6 miscellaneous discrete output (MDO) conditions. Four MDOs are controlled by the VLNC2, and one is assigned to each Main slot. The MDIs are only processed on the VLNC2. Currently, only the VLNC40/42/42B in the MAIN2 slot is capable of using the slot MDO.

• 2 audible and visual Critical/Major and Minor office alarm closures. These office alarm closures are only used by the VLNC2 and the VLNC50/52/55.

• BITS I/O

  A derived DS1/E1 output is available when a VLNC50/52/55 circuit pack is in the MAIN 1 slot or MAIN 2 slot. When a VLNC60/VLNC61/VLNC62/VLNC64 is installed in either the MAIN 1 slot or MAIN 2 slot, DS1/E1 BITS input is supported.
