These are connected via T1 lines with the central office switch, replacing older analog two-way and direct inward dialing ( DID ) trunks.

However, typica are not as well camouflaged against foliose lichens common on tree trunks ; though they are camouflaged in human wavelengths, in ultraviolet wavelengths, foliose lichens do not reflect ultraviolet light.

All communications trunks are now digital.

Both trees have toppled sideways, the younger tree in the Great Storm of 1987, and are now earthed up round the trunks, but continue to fruit every year.

In addition, since stripping removes the saphenous main trunks, they are no longer available for use as venous bypass grafts in the future ( coronary and / or leg artery vital disease )

In crocodilians, there is a small opening, the foramen of Panizza, at the base of the arterial trunks and there is some degree of mixing between the blood in each side of the heart, during a dive underwater ; thus, only in birds and mammals are the two streams of blood – those to the pulmonary and systemic circulations – permanently kept entirely separate by a physical barrier.

In land-line telephony, AIOD leads are Terminal equipment leads used solely to transmit automatic identified outward dialing ( AIOD ) data from a PBX to the public switched telephone network or to switched service networks ( e. g., EPSCS ), so that a vendor can provide a detailed monthly bill identifying long distance calling usage by individual PBX stations, tie trunks, or the attendant.

Demand assignment is similar to conventional telephone switching, in which common trunks are provided for many users, on a demand basis, through a limited-size trunk group.

The tables assign the trunks that are to be used to reach each switch code, area code, and International Access Prefix ( IAP ), usually with one or two alternate routes.

In large scale telecommunication networks such as telephone network trunks, microwave relay networks, cable television systems, and communication satellite links, large bandwidth capacity links are shared by many individual communication channels by using heterodyning to move the frequency of the individual signals up to different frequencies, which share the channel.

With the advent of digital trunks, supervision signals are carried by robbed bits or other bits in the E1-carrier dedicated to signaling.

They are found particularly in the rainforests of the tropics and temperate zones, where they live among moss cushions and leaf litter, under tree trunks and stones, in rotting wood or in termite tunnels.

Many species are ‘ half-barks ’ or ‘ blackbutts ’ in which the dead bark is retained in the lower half of the trunks or stems — for example, E. brachycalyx, E. ochrophloia and E. occidentalis — or only in a thick, black accumulation at the base, as in E. clelandii.

Trees in these regions are generally shorter and more heavily stemmed than in lower altitude forests in the same regions, often with gnarled trunks and branches, forming dense, compact crowns.

So stout are the trees the structure supports that their trunks are eight cubits thick and their height as much as fifty feet ; they bear fruit as abundantly as if they were growing in their natural environment.

The beams are palm trunks, for this type of wood – unlike all others – does not rot and, when it is damp and subjected to heavy pressure, it curves upwards.

They have been regularly pollarded for many years and both trunks are hollow.

There are several styles of sweat lodges that include a domed or oblong hut similar to a wickiup, or even a simple hole dug into the ground and covered with planks or tree trunks.

Once the trees are about 25 years old the cork is stripped from the trunks every ten years.

ISDN signaling is used primarily on trunks connecting end-user private branch exchange ( PBX ) systems to a central office.

The WALBURN family ( KG-81, KG-94 / 194, KG-94A / 194A, KG-95 ) of equipment consists of high-speed bulk encryption devices used primarily for microwave trunks, high-speed land-line circuits, video teleconferencing, and T-1 satellite channels.

It is primarily used on international trunks in the phone network and is the standard codec used in DECT wireless phone systems.

Some were characterized by thick trunks and pinnately compound leaves that bore a superficial resemblance to those of cycads, differing primarily in stomatal arrangement.

high-capacity cable and microwave radio relay trunks

For the most part, higher-capacity systems, such as two-way video communications or terrestrial microwave telephone and data trunks, have been limited and confined to UHF or microwave and to point-point paths.

* their litter, stems and trunks slow down surface runoff ;

In cold climates, these trees store starch in their trunks and roots before the winter ; the starch is then converted to sugar that rises in the sap in the spring.

At the beginning of the spring thaw, they used stone tools to make V-shaped incisions in tree trunks ; they then inserted reeds or concave pieces of bark to run the sap into buckets, which were often made from birch bark.

Syrup makers first bored holes in the trunks, usually more than one hole per large tree ; they then inserted wooden spouts into the holes and hung a wooden bucket from the protruding end of each spout to collect the sap.

There are some leaves, some tree trunks, and, in the background, a river in which a chemise-wearing woman bathes ; in the foreground, two young men are seated across from a second woman who has just exited the water and who dries her naked skin in the open air.

Many species form short trunks ; in the case of the genus Todea, they are sometimes considered as tree ferns because of the trunk, although it is relatively short.

They can also be useful if encountering a " circuits busy " condition when all long distance trunks are tied up ; a CAC allows selection of an alternate carrier, which may have other open long-distance trunks.

World heavyweight boxing champion Max Baer fought with a Star of David on his trunks as well, notably, for the first time as he knocked out Nazi Germany hero Max Schmeling in 1933 ; Hitler never permitted Scmheling to fight a Jew again.

They often climb up tree trunks in a helical path, hopping with their feet together ; their toes are long and tipped with strongly curved claws for gripping.

Other Bishops, Priests, Religious men and women going up a steep mountain, at the top of which there was a big Cross of rough-hewn trunks as of a cork-tree with the bark ; before reaching there the Holy Father passed through a big city half in ruins and half trembling with halting step, afflicted with pain and sorrow, he prayed for the souls of the corpses he met on his way ; having reached the top of the mountain, on his knees at the foot of the big Cross he was killed by a group of soldiers who fired bullets and arrows at him, and in the same way there died one after another the other Bishops, Priests, Religious men and women, and various lay people of different ranks and positions.

In Spain, Galland first displayed his unique style ; flying in swimming trunks with a cigar between his teeth in an aircraft decorated with a Mickey Mouse figure.

Not a tree was standing ; the denuded trunks, scorched and bare, lay prone, torn out by the roots.

The feathers of the tail are rigid and are used for supporting the body when climbing tree trunks ; the tail can support most of the body weight and birds that lose their tail find climbing difficult.

" His comedy routine incorporates dozens of props stored in large trunks on stage ; his prop jokes commonly consist simply of his pulling out a prop, describing it in a one-liner, and tossing it away.

Green conducted much of her business at the offices of the Seaboard National Bank in New York, surrounded by trunks and suitcases full of her papers ; she did not want to pay rent for an office.

They eat insects, found in leaf litter or on tree trunks ; they may also eat small lizards or tree frogs.

This genus is mostly medium to robust in size but also includes a few dwarf species ; trunks are solitary in four species, suckering and clumped in nine, of which one has a prostrate ground trunk.

The Pitch Pine is not a major timber tree, due to the frequency of multiple or crooked trunks ; nor is it as fast-growing as other eastern American pines.

They have long lower incisors, which allow them to chew holes in tree trunks and branches to harvest the gum inside ; some species are specialised feeders on gum.
