Configuring Personal Handyphone System (PHS)
Personal Handyphone System (PHS) is a mobile telephone service currently offered in Japan
and other Asian countries only. In addition to voice communication, PHS offers data
communication at a bandwidth of 32 Kbps, and can thus provide Internet access as well as
voice service.
A MAX unit supports PHS through PHS slot cards, each of which supports 8 or 16 concurrent
PHS users. The unit supports up to two cards on the MAX 3000 and up to six cards on the
MAX 6000.
You need to enable the software functionality on the MAX through a hash code upgrade. When
you have installed this hash code, the System Options menu displays PHS Installed.
Otherwise, the System Options menu displays PHS Not Installed. Contact your Lucent
sales representative for details about enabling PHS support.
No further configuration is necessary. For example, when you boot up a MAX 3000 with a
PHS card in slot 2 or 3 and the unit software enabled, the following menu appears:
Main Edit Menu
00-000 System
10-000 Net/T1
20-000 Empty
30-000 PIAFS-8
40-000 Ethernet
50-000 Ether Data
60-000 Serial WAN
70-000 V.90 S56 III Modem
Personal Internet Access Forum Standard (PIAFS) is a protocol designed to support
connection negotiation, data transfers, and error correction. In the example, the -8 refers to the
slot card’s support of eight concurrent PHS users. A card that supports 16 concurrent PHS
users is also available. That card appears as PIAFS-16 in the Main Edit Menu.
Note: MAX 6000 units support PIAFS protocol version 2.1 for PHS service. This PIAFS
version has an enhanced link-level protocol that supports dynamic switching of data
transmission rates. Depending on bandwidth availability, the protocol will select a 64 Kbps or
32 Kbps transmission rate. Support for PIAFS protocol version 2.1 is controlled with a
hashcode. (MAX 3000 units cur rently support up to 32 Kbps. H owever, the next release of the
MAX 3000 software will support PIAFS version 2.1, with 64 Kbps capability.)
Configuring ISDN BRI network cards
An ISDN Basic Rate Interface (BRI) network interface card supports eight BRI lines. These
lines can provide lower-cost connections to sites that do not require or have access to the
higher-bandwidth T1 or E1 lines. There are two types of BRI network cards: the U and the S
cards. Functionally, they are the same.
You can create multiple, alternative configurations for an ISDN BRI network card, storing
each configuration in a separate Net/BRI > Line Config profile. Only one such profile can be
active at a given time for a given Net/BRI slot. To activate a profile, see “Activating a profile”
on page 2-7. To create a Net/BRI configuration, open a Net/BRI > Line Config profile. You
