Tandem Connections of Wideband and Narrowband Speech Communication Systems Part 2--Wideband-to-Narrowband Link By L. R. RABINER, M. R. SAMBUR, R. E. CROCHIERE, and D. J.

Agencies of the United States government are currently formulating plans for an extensive digital secure voice communication network.

n p H E R E are 14,000,000 telephones in the Bell System, served from 6,800 central offices. Means must be provided to permit a n y one of these telephones to be connected to any of the others.

We introduce a novel class of tandem queueing networks which arise in modeling the congestion behavior of wireless multi-hop networks with distributed medium access control.

The problem of distortion accumulation due to tandem transcodings in a network arises when high-quality, low-rate quantizers (codecs) are introduced into the network.

Reactively sputtered tantalum nitride (Ta sub 2 N) has been investigated as a diffusion barrier between Pd sub 2 Si and aluminum and CoSi sub 2 and Al.

We summarise the main performances of tantalum oxide films fabricated by anodic oxidation of tantalum nitride and tantalum silicide with thickness ranging from 100 to 4500 Angstrom.

ESD issues related to packaging surface mount devices in tape and reel were examined. ESD damage mechanisms due to the field-induced model and charged- device model (CDM) were investigated.

We propose a new method of ensuring the redundant storage of information on tertiary storage, especially tape storage.

We demonstrate a novel tapered fiber that allows butt coupling to a standard InP ridge waveguide with ~1.8 dB loss, (~1.2 dB if anti-reflection coated).
