10 of 16

•

Ability to generate RAI (yellow alarm) according to the Japanese standard

•

T1 to E1 conversion

Framer/Formatter TDM Interface

•

Independent two-frame receive and transmit elastic stores

•

Independent control and clocking

•

Controlled slip capability with status

•

Support for T1-to-E1 conversion

•

Ability to pass the T1 F-bit position through the elastic stores in the 2.048MHz TDM mode

•

Hardware signaling capability

•

Receive signaling reinsertion

•

Availability of signaling in a separate signal pin

•

BERT testing to the system interface

TDM-over-Packet Block

•

Enables transport of TDM services (E1, T1, E3, T3, STS-1) or serial data over packet-switched networks

•

SAToP payload-type machine maps/demaps unframed E1/T1/E3/T3/STS-1 or serial data flows to/from IP,

MPLS or Ethernet packets according to ITU-T Y.1413, Y.1453, MEF 8, MFA 8.0.0 and IETF RFC 4553.

•

CESoPSN payload-type machine maps/demaps structured E1/T1 data flows to/from IP, MPLS or Ethernet

packets with static assignment of timeslots inside a bundle according to ITU-T Y.1413, Y.1453, MEF 8, MFA

8.0.0 and IETF RFC 5086.

•

AAL1 payload-type machine maps/demaps E1/T1/E3/T3/STS-1 or serial data flows to/from IP, MPLS or

Ethernet packets according to ITU-T Y.1413, MEF 8, MFA 4.1 and IETF RFC 5087. For E1/T1 it supports

structured mode with/without CAS using 8-bit timeslot resolution, while implementing static timeslot allocation.

For E1/T1, E3/T3/STS-1 or serial interface it supports unstructured mode.

•

HDLC payload-type machine maps/demaps HDLC-based E1/T1/serial flow to/from IP, MPLS or Ethernet

packets. It supports 2-, 7- and 8-bit timeslot resolution (i.e. 16, 56, and 64 kbps respectively), as well as N x 64

kbps bundles. This is useful in applications where HDLC-based signaling interpretation is required (such as

ISDN D channel signaling termination, V.51/2, or GR-303), or for trunking packet-based applications (such as

Frame Relay), according to IETF RFC 4618.

TDMoP TDM Interfaces

•

Supports single high-speed E3, T3 or STS-1 interface on port 1 or one (DS34T101), two (DS34T102), four

(DS34T104) or eight (DS34T108) E1, T1 or serial interfaces

•

For single high-speed E3, T3 or STS-1 interface, AAL1 or SAToP payload type is used

•

For E1 or T1 interfaces, the following modes are available:

o

Unframed – E1/T1 pass-through mode (AAL1, SAToP or HDLC payload type)

o

Structured – fractional E1/T1 support (all payloads)

o

Structured with CAS – fractional E1/T1 with CAS support (CESoPSN or AAL1 payload type)

•

For serial interfaces, the following modes are available:

o

Arbitrary continuous bit stream (using AAL1 or SAToP payload type)

o

Single-interface high-speed mode on port 1 up to STS-1 rate (51.84 Mbps) using a single

bundle/connection.

o

Low-speed mode with each interface operating at N x 64 kbps (N = 1 to 63) with an aggregate rate of

18.6Mbps

o

HDLC-based traffic (such as Frame Relay) at N x 64 kbps (N = 1 to 63) with an aggregate rate of

18.6Mbps).

•

All serial interface modes are capable of working with a gapped clock.

TDMoP Bundles

•

64 independent bundles, each can be assigned to any TDM interface
